- About 2-5% of US adults have fibromyalgia.
- It can take an average of 5 years for a person to get a diagnosis of fibromyalgia. It is not well understood, so it must be diagnosed by eliminating other possibilities.
- FM is characterized by: pain in at least 11 of 18 points.
- Sleep disturbances. Trouble getting to sleep, feeling tired when they wake up.
- Irritable bowel or similar symptoms.
- Cognitive problems also called "fibro fog".
- Fibromyalgia often occurs (up to 25-65%) with other rheumatic conditions such as rheumatoid arthritis, systemic lupus erythematosus, and ankylosing spondylitis.
- Fatigue that won't go away.
- Widespread stiffness, aching, and burning sensations. (Of course this will lead to sleeping problems and fatigue!)
- Many patients report they can't get to sleep, and when they do, they wake up still feeling tired. This might be a lack of proper REM sleep. A sleep study might help determine if they get enough REM sleep but many American insurances do not cover this.
- Frequent peeing caused by bladder spasms.
- Researchers have also found abnormalities in the hormone system known as the hypothalamus-pituitary-adrenal gland (HPA) axis. The HPA axis controls important functions, including sleep, the stress response, and depression. Disturbances to the HPA axis is correlated to exposure to BPA. See Chen 2014 below.
- Fibromyalgia can be triggered by infection of Epstein-Barr virus or Lyme disease, chronic physical or emotional stress, hormonal changes, emotional trauma of an accident, "seeing the elephant" (believing you will truly not survive a given situation), or medications.
- Abnornally thick vascular walls, which may prevent enough oxygen from getting to the muscle.
For medical coding using ICD9-CM, FM is usually coded as 729.1, "Myositis and Myalgia, unspecified". Overall, many of the symptoms above seem to be inflammatory symptoms.
FM is not well understood so not all treatments will work well for all, or even a majority of people. Treatments include:
- Aerobic and resistant exercise for the pain.
- Psychological support to deal with the frustration and depression.
- Some medications to address the pain and lack of good sleep. Some medications the FDA has approved for fibromyalgia: Lyrica, Cymbalta, Savella, which all help reduce pain.
- Relaxation training.
- Acupuncture, chiropractic treatments help most patients. But again, many American insurances cover neither.
