Tension, Cluster, Toxic and Migraine Headaches Explained

Saturday, January 23rd, 2010

Types of Headaches

Headaches is one of the major afflictions for which new patients visit my chiropractic office in San Diego. This condition may seem like a minor health issue to those of us who do not suffer from chronic or severe headaches. But they can have a major role as to how the patient and the population are generally affected. Over ten million visits to the doctor in the United States were caused by headaches in 2007 alone, while being a popular excuse for calling out of work and school.

Medications from the doctor offer relief for a little while, but don’t do anything to help the origin. Chiropractic care, on the other hand, works directly at righting the root causes that trigger a multitude of headaches. This piece will delineate the five basic kinds of headaches — tension, toxic, sinus, cluster and migraine — so you may have a better understanding of which kind of headache you might be experiencing.

Tension Headaches

The most common type of headache, by far, is tension headaches. Roughly 4 out of 5 people are subject to tension headaches from time to time, while five percent are subject to tension headaches every day. Tension headaches affect women twice as much as men.

The duration of anywhere from 30 minutes to several days is average for tension headaches. Band-like pain, pressure, or throbbing of the head are the most common symptoms related to this type of headache.

There can be a significant increase in severity with the frequency of the headaches. Emotional stress, depression, not enough rest, poor posture, and/or chiropractic subluxation causing pressure on the nerves are some of the multiple causes for tension headaches. More frequently than otherwise, this kind of headache normally happens due to a mixture of the above mentioned causes.

Toxic Headaches

This is a rare occurrence of a headache in the medical community. Despite this fact, it is often straightforward to identify this category of headache, when occurring as a result to toxin exposure.

Sinus Headaches

Sinus headaches are not unusual, and the pain is localized to sinus cavities around the forehead, eyes, nose, and cheeks. Rather than relieving sinus headaches long term, many medications used for this purpose ironically may exacerbate and prolong sinus conditions.

Cluster Headaches

Cluster headaches are one of the most intense sort of headaches and are normally one-sided. Luckily, though, they are quite unusual and less than 0.1% of people suffer from them. They generally begin prior to age 30 and happen in time periods ranging from 14 days to three months.

These headaches usually occur one to three times per day, lasting for 30-90 minutes. The patient usually awakens from them one to two hours after retiring.

When the cluster period is over, these headaches may disappear for months or years, but the headaches reappear later on. These attacks are considered to be tied to circadian rhythms in the pineal gland and hypothalamus, which controls the resting and awake cycles. This type of headache often occur with spring or fall changes in season.

Migraine Headaches

Migraine headaches, vascular in nature, are caused by variations in the arteries inside and outside the brain. Approximately 28 million Americans suffer with migraines, however approximately 13 million Americans don’t have a diagnosis now. Migraines affect more women than men. Of the ones who have been diagnosed, 25 percent experience at least four episodes per month; 35 percent endure 1-4 attacks per month, and the final 40 percent go through one attack per month or less. Migraines can commonly last from four hours to three days.

There is a family history of migraines in four out of five sufferers from migraines. Children who have one parent who gets migraines have a 50 percent chance of getting them, and if both parents get them, they have a 75 percent chance.

Understanding migraine headache triggers may help avoid future headaches; common trigger factors include weather changes, caffeine, chemical exposure, fatigue or insomnia, and missed meals. Signs may include an aura in the form of light, noise or odor sensitivity; nausea or vomiting; and stomach distress or pain. Additional symptoms of paleness, dizziness, a mild fever, or an upset stomach may manifest in a child with a migraine.

Symtoms of Dehydration and Chiropractic Treatment

Monday, March 16th, 2009

Dehydration is a common problem among adults. I have read studies that indicate that at any one time approximately 75% of American adults are suffering with mild symptoms that result from being dehydrated. Being a chiropractor in San Diego, a desert community, we see many people suffering from ailments ranging from neck pain and headaches to lower back pain with sciatica that all carry some link to dehydration.

The human body is approximately 65% water. By definition, dehydration occurs as the result of excessive loss of water from the body. This occurs as a direct result of not taking in enough water. That is a very superficial explanation of dehydration. In reality, it’s a bit more complicated than that since the body loses electrolytes as well as fluids.

Dehydration is a major issue with our health. A common scene in professional sports is that of the athletes becoming dehydrated and “cramping up”. This cramping of muscles affects us normal people as well. We suffer from back spasms and similar symptoms as a result of dehydration.

Another common symptom of dehydration is headaches. Dehydration has long been known to be a trigger of Migraine type headaches. Many people mistakenly think it occurs only in hot weather and that you’re not dehydrated if you’re not thirsty.

Dehydration Facts:

” It takes an average of 64 to 80 ounces to replace the water our bodies lose in 24 hours.

” Under normal circumstances, how much water we need depends a great deal on the volume of our perspiration and urine output.

” Our bodies’ need for water increases under circumstances such as:

” warmer weather or climate

” living at high altitudes

” increased physical activity

” when experiencing vomiting or diarrhea

” when fevered

” when you have a cold or the flu

” if you have a chronic disease such as uncontrolled or untreated diabetes, kidney disease, alcoholism, cystic fibrosis, or adrenal disorders,

” if you are taking some medications. Always check your prescription information.

” during long air flights

” Losing as little as 1 to 2% of body weight can result in dehydration.

” Losing 3 to 5% can negatively impact reaction time, concentration and judgment

” Losing 9 - 15% results in severe dehydration and is life-threatening.

Dehydration Symptoms:

” Excessive thirst

” Fatigue

” Muscle weakness

” Headache (or, in the case of Migraineurs, Migraine)

” Dizziness

” Less frequent need to urinate and decreased output

” Darker colored urine (should be nearly clear to pale yellow)

” Confusion

” Increased heart rate and respirations

” Skin that doesn’t snap back when pinched and released

” Children may exhibit additional symptoms:

” Absence of tears when crying

” No wet diaper for three hours or longer

” Irritability

” Lethargy

” Fever

When caught early, dehydration can usually be treated at home. Common treatments include:

” Mild dehydration: rehydration by drinking fluids including sports drinks, which rehydrate by providing not only fluid, but also electrolytes and salt. In children, products such as Pedialyte may be recommended as it also contains carbohydrates to help absorption in the intestinal tract. Coffee, tea, and soda should not be used for dehydration as the caffeine in them can actually be dehydrating.

” Moderate dehydration: rehydration may suffice, but IV fluids may be required.

” Severe dehydration: Immediate action must be taken, treating the situation as a medical emergency. Hospital treatment is necessary for IV fluids to rehydrate more quickly and efficiently and to allow observation.

As with most ailments, it’s better to prevent dehydration than to treat it. Here are some preventative steps you can take:

” Drink plenty of fluids and eat foods high in water. Fruit contains the most water, followed by vegetables, meat, then grains with the least.

” Choose your beverages wisely. Caffeine and alcohol can be dehydrating. For some people, too much fruit juice can cause diarrhea, which can be dehydrating.

” If you’re planning a day with more significantly exercise than usual, begin hydrating the day before.

” Sports drinks can help maintain electrolyte balance, but be aware of the sugars in them.

” Plan outdoor activities for cooler parts of the day.

” If you’re organizing outdoor activities, provide shaded areas.

” When you’re ill, be sure to continue drinking fluids, and get additional fluids if you have a fever or are vomiting or have diarrhea. Call your doctor for help with vomiting or diarrhea if necessary.

Medical Myths Overheard At The Chiropractic Office

Tuesday, March 3rd, 2009

In my San Diego based Chiropractic clinic, I hear wives tales regarding health and fitness all the time. The one that I hear most often doesn’t have anything to do with neck pain or back pain - it has to do with knuckle cracking. It seems that almost everyones’ parents have told them “Don’t crack your knuckles, they will get big and full of arthritis when you are older!” Believe it or not, this is not true. Cracking joints that are weight bearing ie, your neck, back, knees and ankles, etc can be harmful if you are not a trained chiropractor, but cracking your knuckles is only irritating to other people.

A study was just released that examined 7 common medical myths that are being circulated today. They are as follows:

Two US researchers took seven common beliefs and searched the archives for evidence to support them.

Despite frequent mentions in the popular press of the need to drink eight glasses of water, they found no scientific basis for the claim.

The complete lack of evidence has been recorded in a study published the American Journal of Psychology, they said.

The other six “myths” are:

Reading in dim light ruins your eyesight.

The majority of eye experts believed it was unlikely to do any permanent damage, but it might make you squint, blink more and have trouble focusing, the researchers said.

Shaving makes hair grow back faster or coarser.

It has no effect on the thickness or rate of hair regrowth, studies say. But stubble lacks the finer taper of unshaven hair, giving the impression of coarseness.

Eating turkey makes you drowsy.

It does contain an amino acid called tryptophan that is involved in sleep and mood control. But turkey has no more of the acid than chicken or minced beef. Eating lots of food and drink at Christmas are probably the real cause of sleepiness.

We use only 10 per cent of our brains.

This myth arose as early as 1907 but imaging shows no area of the brain is silent or completely inactive.

Hair and fingernails continue to grow after death.

This idea may stem from ghoulish novels. The researchers said the skin dries out and retracts after death, giving the appearance of longer hair or nails.

Mobile phones are dangerous in hospitals.

Despite widespread concerns, studies have found minimal interference with medical equipment.

The research was conducted by Aaron Carroll, an assistant professor of pediatrics at the Regenstrief Institute, Indianapolis, and Rachel Vreeman, fellow in children’s health services research at Indiana University School of Medicine.

I hope that you enjoyed this information. Happy Holidays!

Work Station Ergonomics - Setting Up Your Work Space

Thursday, February 12th, 2009

The study of workstation ergonomics tells us that the objects that we use most often should be located closest to your body and accessed easily, without awkward body positions or movements. Repeated reaching or prolonged fixed postures that involve leaning forward from your chair are stressful and fatiguing.

Some people are aware of computer ergonomics and have purchased various ergonomic devices. These devices, such as keyboard trays, gel mouse pads, and ergonomic keyboards rarely provide solutions to the big picture of computer ergonomics. These items must work with each other in order to produce a significant reduction in postural stress. For example, an ergonomic mouse is of little use if it is positioned in an area that requires reaching and stretching in order to operate it. Limiting reaching and stretching for desk items is essential to maintaining a healthy ergonomic environment.

The most frequent complaint that I have seen in my office is due to computer work is the combination of mousing and reaching to the desk for the mouse.

Most computer stations are designed in a way that involves the worker operating the computer mouse on a pad on the desk. Reaching to the desk for the mouse places direct stress on the joints and soft tissues of the neck, shoulder, elbow, wrist and hand. Additionally, reaching forward for the mouse stresses the lower and middle back.

So How Does Reaching for the Mouse Set the Stage for Injury?

Reaching for the mouse causes you to lean forward in your chair, extend your arm and support the weight of your body through your extended arm.

The stresses placed on the human frame when reaching for the mouse are easily identified. Contrary to popular belief, sitting, which most people believe is relaxing, is hard on the back. Sitting for long periods of time can cause increased pressure on the discs of the spine.

In recent years, studies on postural stress have indicated that we should be sitting upright with our hips flexed at 90 degrees. As it turns out, the most up to date studies show that a slightly reclined sitting posture with the hips flexed at 100 to 115 degrees is ideal if you have to sit at a desk. If your mouse is not positioned close enough to your body, you will have to reach for it. Reaching for your mouse stresses your back by reducing the angle of your hips.

Next, we have to look at the effects of reaching on the neck and shoulder. When the mouse is being operated at a distance that makes the operator reach, the shoulder extends forward and the shoulder blade abducts (rotates forward). This position stretches the muscle groups that connect the medial portion of your shoulder blade to your spine and the superior portion of your shoulder blade to your neck. In the short term, this stretch aggravates the affected muscle groups causing spasm, fatigue, headaches and stiffness in the neck and shoulder. In the long term, this position creates a condition called a “stretch weakness” resulting in muscular imbalance, trigger points and chronic variations of the conditions listed in the prior sentence.

Lastly, placing the mouse too far away, too low, or too much on one side can cause shoulder, wrist, elbow, and forearm discomfort. When the operator is forced to reach for the mouse, his / her body weight shifts forward and ultimately results in weight bearing stress on the extended arm. Spending prolonged periods of time leaning on an extended arm is an unnatural and destructive posture that will eventually lead to the development of a repetitive stress syndrome; likely resulting disorders would include tendonitis of the wrist, elbow or shoulder.

Repetitive Stress Injuries: San Diego Chiropractic

Wednesday, February 11th, 2009

In addition to neck pain, back pain and headaches, my San Diego chiropractic office provides treatment for many patients with various types of repetitive stress injuries. This post will continue from where the last one left off and will describe what repetitive stress injuries are.

A Repetitive Stress Injury is a kind of catch all phrase for many conditions. Carpal Tunnel Syndrome, Tenosynovitis / DeQuervain’s Syndrome, Tendonitis, Thoracic Outlet Syndrome, Trigger Finger, Myofascial Pain Syndrome and Chronic Sprain / Strain are some of the actual diagnosis that are rendered in my office. All of these conditions are serious and in many cases can cause great pain, permanent disability and sometimes loss of employment.

Repetitive Stress Injuries occur from repetitive movements involving a specific set of muscles and joints. RSI injuries are the result of an accumulation of stress and strain that causes irritation, inflammation, and eventually pain or other disability. A good analogy used to characterize the onset of RSI would be the “straws on the camels back” saying.
Initially, RSI affects the soft tissues of the involved joint(s). Soft tissues include muscles, nerves, ligaments and tendons. However, if left untreated for long periods of time, the involved joint can become arthritic and form bone spurs resulting in permanent damage to the joint.

While various occupations ranging from meat cutters to construction workers develop RSIs that result from the typical duties of their professions, the most frequent cause of these injuries involve computer work. The constant muscular demands of keyboarding and mousing combined with the postural stress of confinement in an office chair with one’s neck and back held in prolonged fixed positions has resulted in an epidemic of injuries that includes hand pain, wrist pain, arm pain, neck pain, back pain and shoulder pain.

I hope that you are finding this information helpful. My next post will continue this series and will describe the basics of workstation ergonomic set-ups.

Repetitve Stress Injuries

Computer Stress and Ergonomics: A Chiropractors Perspective

Saturday, February 7th, 2009

Does computer work seem much more difficult (physically) than it should be?

The patients in my San Diego chiropractic practice often seem perplexed by the fact that they can be injured doing such sedentary work as computer work. Most are of the opinion that it takes a forceful and traumatic incident to result in injury.

Unfortunately, this is not the case. National statistics point to the computer as a major contributor to lost days at work due to injury. I see the same thing in my San Diego Chiropractic office. Neck pain, shoulder pain, wrist pain, hand pain and back pain are common among those who don’t have the proper ergonomic set-up of their computer stations. That being said, some people get these symptoms regardless of their ergonomic set-up and must evaluate many other contributing factors in order to relieve the stress.

Computer ergonomics is the study and / or implementation of workstation design with the purpose of reducing or eliminating physical stress.

My interest in repetitive stress syndromes began approximately 10 years ago when my practice started seeing a much greater number of people suffering from the effects of computer / keyboard work. Despite all of my training and continuing education related to these types of injuries, I quickly realized that traditional treatment for this type of injury was marginally successful at best.

Any type of therapy was going to have to include the application of basic ergonomic principals to the patient’s work environment.

I am of the opinion that treatment alone or application of ergonomic principals by themselves is not going to resolve a repetitive stress injury.

Over the next several weeks I will write a series of articles that will address the implication of workstation ergonomics and injury resulting from postural stress secondary to use of the computer mouse.

Specifically, the following will be addressed:

1) What repetitive stress injuries are

2) What role do work station ergonomics play in injury

3) How reaching for the mouse sets the stage for injury

4) What are the symptoms of repetitive stress injury

5) How you can avoid mouse reaching injuries

Treating Arm Pain in San Diego - Chiropractic

Thursday, January 29th, 2009

Have you ever slept on your arm and had it fall asleep? Imagine if it just felt like that all the time.

A few months ago I had a young lady come to my San Diego Chiropractic office with these complaints. In addition to numbness and tingling, she had neck pain, shoulder pain, arm pain, wrist pain and hand pain. She also complained of weakness in her left hand, which was resulting in clumsiness and was affecting her work as an executive secretary.

These complaints are seen with regular frequency in my office. The process is a familiar one and common with many musculoskeletal conditions that involve the nervous system.

Usually, postural stresses such as leaning over a desk or computer will eventually irritate a specific joint in the spine. The irritation of the joint causes inflammation of the muscles and ligaments that surround that joint. This inflammation will cause compression of the local nerves resulting in pain and muscle spasm. If the nerve compression persists, numbness, tingling and weakness of the related muscles will follow.

This patient was displaying signs and symptoms of long-term nerve root compression that involved her left arm and hand.

We treated her with chiropractic manipulations that were delivered with the specific goal of eliminating the nerve root compression. She was also treated with ice packs, hot packs, electrical muscle stimulation and ultrasound in order to address the soft tissue inflammation. In addition to in office care she was given a set of stretches and exercises for at home therapy and advised to use ice packs daily for twenty minutes per session.

It took approximately eight weeks of active care, which is three treatment visits per week, to relieve 90% of her pain and 90% of her left arm weakness. The rest of her symptoms will resolve with at home therapy and chiropractic care delivered on an as needed basis for flair-ups that will occur in the future.

This is just one example of the many different types of cases that resolve with chiropractic care in my office.

What Are Proper Ergonomics?

Saturday, July 19th, 2008

One of the services that my San Diego Chiropractic Clinic offers is ergonomic evaluations of my patient’s work stations.  Some of the work stations that I evaluate are absolutely, without question, injury provoking.

So what Are Proper Ergonomics?

The relationship between a worker and his equipment is termed ergonomics.  Ergonomics dictates that the shape, size, height, position, etc of objects that we work with should “fit” our physical requirements to help eliminate any stress that they otherwise may bring us.

In your work world, ergonomics should first be applied to the items that you use the most.  Those items should be placed close to your work space in order to eliminate unnecessary reaching and stretching.  For instance, if you use the phone often during the day, it should be placed within easy reach of your chair.  If you use it frequently, you should consider getting a headset in order to eliminate any reach.  These principals can be applied to any item that you use frequently during the day.  Another example would be a stapler.  If you staple often, keep it close.  If you staple frequently, keep it close and get an electric model to eliminate the stress as much as possible.   When operating a computer, there are special considerations regarding ergonomics.

The basics include:

  1. Your keyboard should be placed directly in front of you.
  2. Your keyboard should be at the same height as your elbows when they hang restfully at your sides.
  3. Your keyboard should be far enough away to create an angle in your elbows of somewhere between 90 and 110 degrees.
  4. When using your keyboard, your wrists should either be straight or slightly flexed.
  5. Your mouse should be within easy reach.  The same rules apply for your mouse as for keyboard positioning.  Years ago I patented an ergonomic mouse pad that attaches to the armrest of your chair.  When properly attached, the mouse is in the perfect location.  This mouse pad, called the ErgoNav can be purchased through the internet and is distributed by Comfort Keyboard Systems.
  6. Your monitor should be directly in front of you.  Your eyes should be at the top third of the monitor when you are looking straight ahead.
  7. Your knees should be bent at 90 degrees with your feet on the floor or on a foot support.  Your hips should be slightly open, and angle between 125 and 135 degrees is ideal.

In addition to the list above, there are many considerations when one is attempting to make a work station friendlier.  Because of our heavy educational emphasis in human biomechanics, chiropractors are very good at eliminating stress from work stations.
