Headaches and CFIDS
Taming the pain, easing the pressure
By Kim Kenney

“I don’t remember ever having had a headache before CFIDS. About eight months after a very acute onset of flu-like symptoms and memory and concentration problems later diagnosed as CFIDS, I had my first headache. At the time I was already spending 20 hours a day in bed — wrung out, brain-fogged and very weak. I didn’t think it was possible to feel any worse. I was wrong; when I have a headache I am at my very worst. Some-times they last several days.” — Carra, describing her tension headaches

“Headache of a new type or severity” is one of the eight symptom criteria listed in the international case definition for chronic fatigue syndrome. Headache is very common in the general public: Ninety percent of men and 95 percent of women report having had at least one headache in the past year. However, for people with CFIDS (PWCs), headache is layered on top of other symptoms and can profoundly affect function and quality of life. Researchers and clinicians are learning more about how to treat and prevent headache, so new options for diminishing its impact for those with CFIDS warrant exploration.


Types of headache

Tension headaches affect 75 percent of those who get headaches. It is generally defined as a steady pain on both sides of the head and is caused by tightening of the shoulder, neck and head muscles. Soreness and pressure can accompany the pain and it may be brought on or made worse by stressful events or a hectic day. Relaxation techniques can be helpful as part of an overall treatment program, discussed in more detail below.

Migraines are the most debilitating form of headache; an estimated 25–30 million people in the U.S. have experienced them. Twenty percent of sufferers describe a distinctive group of symptoms that immediately precedes the throbbing pain of a migraine — visual disturbances (e.g., flashing lights or “floaters” in the field of vision), nausea and increased sensitivity to light, sound and odors. These symptoms are called an “aura” and usually fade as the headache sets in. Cutaneous allodynia, hypersensitivity to contact with the skin of the face, head and forearms, is a recently recognized feature of migraine attacks. (See box on p.6) Migraines are thought to be caused by chemical and/or circulatory changes in the brain. There is often a family history of migraine and set of activities or circumstances that trigger the start of a migraine attack. Prevention is a key treatment strategy.

Cluster headaches affect more men than women and account for just one percent of all headaches. These headaches are short-lived, but come in groups — hence the name. They are usually localized to one side of the head and may be accompanied by a bloodshot eye or runny nose. Cluster headaches are described as being more severe and intense than other types of headache.

Rebound headaches occur as a response to overuse of headache medications; as the medicine wears off, the pain builds. This can lead to escalating use of painkillers if not treated appropriately. The term secondary headache refers to headache caused by another organic condition, such as infection (e.g., strep often causes headache) or increased pressure in the brain due to a tumor or other structural abnormality.

Headaches can also signal inflammation and/or infection of the sinus cavity, or can result from problems with vision or improper vision correction. Providers generally try to rule out these possibilities before beginning a headache treatment program.

Headache types have some overlapping features and it is possible for an individual to experience more than one type of headache (e.g., a person who has frequent tension headaches may also get occasional migraines). Being able to distinguish between headache types enables the patient and provider to determine which treatment strategies will be most effective in combating pain and preventing future headaches.


Assessment
There is no objective sign or diagnostic test for headache, so diagnosis is based on medical history and patient reports. While primary care providers can often manage routine headaches, there are a growing number of professionals who specialize in the treatment of headache disorders. Neurologists, pain management specialists, physiatrists, psychologists and other professionals may participate in advanced education or research about the diagnosis and management of headache. Additionally, headache clinics may offer a one-stop, multi-disciplinary approach to patient care.

The provider will generally rely on information collected in the patient interview to determine if brain scans or other tests are warranted. If the headache pattern, presence of other symptoms and/or an abnormal neurological exam suggest encephalitis (swelling of the brain and spinal cord) or tumor, the doctor may order an MRI or CT scan before determining a course of treatment. The physical exam can reveal signs of muscle tightness, sinus cavity tenderness, blood pressure disorders and other clues as to underlying sources of head pain.

Tools that help track headache triggers, frequency, severity and impact on function can be very beneficial in establishing an accurate diagnosis and developing a treatment plan. Keep a headache diary for several weeks, making note of how and when the pain starts, what other symptoms accompany it, what might have provoked it (e.g., environmental conditions, activity that preceded it, foods or drinks taken before the headache, etc.) and how long it lasts. You may want to note such things as the weather, barometric pressure, day of the menstrual cycle — all have been reported to trigger headache in some individuals. Also record what treatment you undertake, whether it’s medication or stress relief techniques, and what seems to reduce, if not alleviate, the pain. Bring the diary to each appointment with the treating provider.

The Migraine Disability Assessment (MIDAS) is a five-item questionnaire “scored” to help determine the level of disability caused by headaches over the past three months. The Headache Impact Test is a more in-depth questionnaire developed to provide a headache profile for patient and provider to use in setting a treatment plan and tracking changes in headache patterns. Both can be found online through the National Headache Foundation, at www.headaches.org.


Treatment
There are many, many different ways to treat headaches. These strategies are usually broken into (at least) two categories: acute or abortive (treatment that helps end or diminish a headache once it occurs) and preventive or prophylactic therapy (that helps reduce frequency with the eventual goal of eliminating headache). Further, treatment can be divided into other categories: medical, behavioral and complementary/alternative. 

Most sufferers find that achieving success requires a combination of approaches, and that different treatments may be effective at different times. It often requires a considerable amount of trial and error, working with a provider or therapist to suggest logical combinations, monitor success and make changes. Using a chart like the one on p.4 can help you track what you try and how well it works. The example contains generic names of commonly prescribed medications and a general guide for how each of the other modalities is used to treat headache.


Medications
All medicines carry side effects and can interact with other drugs, supplements and herbal preparations being used. Because so many people with CFIDS are sensitive to even low doses of medications, it’s essential to communicate openly with your health care provider to assess the possible effects, interactions and trade-offs associated with medicines. Some drugs used to treat headache can disrupt sleep while others have sedating effects. The goal should be finding the most effective medication using a dose with the fewest side effects. Here is an overview of some of the medicines used for headache:

The drugs most commonly prescribed to treat the pain of a headache after it’s already started are “triptans” and non-steroidal anti-inflammatory drugs (NSAIDs). Triptans are among the newest drugs developed for migraine. They moderate the levels of serotonin and constrict blood vessels in the brain. Due to the frequent occurrence of nausea with headache, many of these medications come in a variety of forms, including pill, nasal spray, suppository and injection. Effectiveness of a given medication may vary based on the method of delivery (e.g., nasal spray may be more effective than tablet, even at the same dose).

As with treatment for other forms of pain, there are numerous analgesic medications often tried in increasing dosages and strengths. Providers usually begin with over-the-counter NSAIDs, a few of which have been formulated for migraine, often adding caffeine to boost its effect. Narcotics are generally reserved for short-term relief of the most treatment-resistant forms of pain. Concerns about developing tolerance, dependence and addiction to pain-killers are expressed by many patients and providers; taking these medications only as directed can minimize the likelihood of these problematic outcomes.

Anticonvulsants, beta-blockers and antidepressants are frequently used to help prevent headaches by regulating “switches” in the brain that control certain activities. A few have been approved for use in headache while others are considered “off-label” treatments. This classification may impact medical insurance reimbursement; some medical plans will not pay for medications that are not used as specifically prescribed. If so, consult with your provider about other covered treatments that may be appropriate substitutes.

Trigger point injections and Botox have shown some benefit in treating headache. For tension headache caused by knotted, painful muscles, periodically shooting a local anesthetic such as lidocaine into the most gnarled sites can relax the muscle and speed relief. The injection itself is unpleasant, but can be made less so by alternating heat and ice at the site and stretching after the immediate pain subsides. Botox, a neurotoxin popular for smoothing age-related wrinkles, is gaining fans as a treatment for severe chronic headache. One course of treatment can last three to four months. Cost and insurance reimbursement vary, as does acceptance of this use of the broadly promoted “vanity” drug. 


Non-medicinal approaches
As indicated on the treatment chart, there are a vast number of other strategies used to reduce the impact headache has on function and quality of life. Some are no-cost or low-cost, such as deep breathing and applying coldheat and ice to the head. Others, like practicing good sleep hygiene, require more discipline or the help of a professional, as with acupuncture or physical therapy. Some people choose to use these strategies as an adjunct to medications, while others use them in place of a more traditional medical approach.

Either way, the goal should be to reduce the pain associated with the headache as well as its frequency and duration. Avoiding activities, environments or substances that trigger headache is essential. Reducing stress and learning about proper body positioning during periods of rest and work can help the body care for itself. The headache diary (discussed earlier) can be an important tool in identifying patterns and triggers and tracking what helps and what doesn’t.


A bright horizon
Progress in understanding and treating headache is occurring faster than ever, thanks to recognition of the significant disability and cost associated with inadequately treated headache and the large and lucrative market for pharmacologic treatments. About half of all people with CFIDS report headache to be a substantial component of their overall symptom complex — for this segment of the patient population improved management of headache can lead to better function and quality of life.

For other PWCs, the strategies used to treat headache may be beneficial in addressing other symptoms — joint and muscle pain, impaired concentration, etc. Both conditions involve a highly individualized approach to treatment, patience and persistence on the part of patient and provider, and constant assessment of treatment successes and failures. With luck, the payoff is reduced suffering and disability until more effective, lasting solutions are available.

Guidelines for Managing Acute Migraine Headache

Clinicians are advised:

  • To educate migraine patients about their condition and its treatment and encourage patients to participate in treatment decisions;
  • That when patients respond poorly to NSAIDs or combination analgesics such as aspirin, acetaminophen, and caffeine, migraine-specific agents, such as a triptan, dihydroergotamine, or ergotamine, should be used;
  • That patients who experience nausea and vomiting early in migraine should be selected to receive non-oral medication formulations;
  • That patients who have been refractory to treatment should be considered for self-administered rescue medications; and
  • To avoid causing medication overuse headache, also known as rebound or drug-induced headache.

Multiple well-designed randomized clinical trials support recommendation of the following medications:

  • Oral combination opiates
  • Dihydroergotamine nasal spray
  • NSAIDs (oral) and combination analgesics
  • Butorphanol nasal spray
  • Triptans

“Even my hair hurts…”

In an article published Sept. 4, 2003 in Headache: The Journal of Head and Face Pain, cutaneous allodynia (CA) is described in detail as a feature of migraine headache. The paper explores the decades-old observation that patients avoid hair brushing and touching the scalp, shaving, brushing teeth and wearing glasses, contact lenses, earrings, or tight clothes during migraine attacks. This heightened sensitization is also described by people with CFIDS in the acute phase of the illness and/or during a relapse.

Research shows that a cascade of complex chemical reactions occurs in each phase of migraine, and that CA may be responsible for reports of pain in the head and neck area that frequently extends beyond the “headache” region. The presence of this symptom in about 75 percent of migraine sufferers suggests that the pathophysiology of migraine may involve peripheral, central brainstem and thalamic neurons. Further studies indicate that treatment of CA is best accomplished by giving abortive drugs (particularly triptans) within 30–60 minutes of the onset of migraine pain. Early intervention ends the attack more effectively and can help prevent the onset of CA. The same study reported that later intervention was generally unsuccessful in treating CA once it starts.
