The Fibromyalgia syndrome (FMS)  is one of the diseases that were reputed to be all in your head.  Not any more, at least not  in the “imaginary” sense. This was particularly,  aggravating because it could be so painful. It is called a syndrome because it manifests itself in a similar way to patients, but could have multiple causes. Actually, even though the pain is primarily at the sensitive points of the figure below ( uploaded from Wikipedia Commons), it does have something to do with your brain [1].

However, brain alterations do not seem to prove the primary cause of Fibromyalgia is in the brain. Quoting the Neuroscientist paper:

“…Despite the numerous cerebral alterations, fibromyalgia might not be a primary disorder of the brain but may be a consequence of early life stress or prolonged or severe stress, affecting brain modulatory circuitry of pain and emotions in genetically susceptible individuals…”

Fibromyalgia also induces  a loss of gray matter in the FMS afflicted brain [1a]. Gray matter is a critical component that  contains neuronal cell bodies, as the other component, white matter,  contains mostly the axons or nerve connections. The photograph below is a lateral view of a real brain, not a sketch. Nine times more women than men are afflicted.

Fig (1): Lateral View of Dissected Brain (John A Beal, Wikipedia)

 

 For the fun of  it, here is the key to the numbers on Fig (1) identifying the main brain  regions..Skip if you are in a hurry…

  1. entriculus lateralis, Cornu frontale
  2. Ventriculus lateralis, Pars centralis
  3. Calcar avis
  4. Ventriculus lateralis, Cornu occipitale
  5. Trigonum collaterale
  6. Eminentia collateralis
  7. Hippocampusduloxetine, milnacipran
  8. Ventriculus lateralis, Cornu temporale
  9. Capsula interna
  10. Nucleus caudatus

As you can see a lot  of the gray matter is at the surface of the brain. Loss of gray matter is associated with chronic pain [2,3] aging [4] or trauma [5]. So, maybe, gray matter loss is not the hallmark of a necessarily degenerative process. That is, if aging is not a degenerative process, but I digress…

In terms of manifestations, FMS is mostly pain without an apparent cause  [6], and particularly focused on tender points such as shown in Fig (2) below . But it also can include: fatigue, sleep disturbance,  joint stiffness. bowel and bladder abnormalities, numbness and tingling and cognitive dysfunction.

So, are there  treatments for FMS ? The answer is a qualified yes

Academia classifies the overall pain reduction as : “…full response (at least a 50% change), response (30-49% change), and no response (less than a 30% change.” [7]. This is the kind of pain reduction you can expect from the drugs on the market. Let us do the math:  a 40% reduction means 60% remains. Hmmm….

The most common drugs are [7-11]:

  1. Lyrica/Pregablin  or Gabapentin / Neurontin [9] succeed in decreasing the pain level by 30% to 50% in many people, 30% being more likely . They both are anticonvulsants and were used initially against epilepsy, and are used commonly against neuropathic pain
  2. Duloxetine (Cymbalta) is an antidepressant serotonin-noradrenaline reuptake inhibitor (SNRI)
  3. Milnacipran (Savella) also an SNRI, but interestingly approved in the US only for FMS

More drugs against FMS can be found in [11]. Since FMS is a syndrome, every patient can respond substantially differently to the drugs, hence the variety. But again,  in most cases the 30% to 50 % pain reduction is the goal. I have not seen a study claiming 75% or better. FMS also usually affects sleep and sometimes cognition, so your doctor has to balance all your needs and your tolerance to the  side effects. For example, use of Lyrica can bring about dizziness, sleepiness, blurred vision, dry mouth, swelling of the hands and feet, weight gain.

So many have turned to alternative medicine for help. These Complementary and Alternative Medicine (CAM) include three categories:

  1. Nutrition, herbs and supplements
  2. Massage
  3. Mind Body techniques and Tai-Chi

Nutrition, herbs and supplements: 

Cathy Wong, in about.com [12]  has an excellent article on this.

  • Magnesium: “…Magnesium, along with malic acid (a fruit acid found naturally in apples) are often suggested for people with fibromyalgia because they are both needed for the generation of energy in cells in the form of adenosine triphosphate (ATP)…”
  • Note:  The FMS benefits seem to be strongly dose dependent, up to 300 mg magnesium and 1200 mg malic acid per day) for 6 months.
  • A study [13] of people with poor sleep shows lower Magnesium levels that can be remediated by supplementation. FMS patients do suffer from poor sleep patterns
  • Vitamin D : While there is a vitamin D deficiency both in women with FMS and and  in men with musculoskeletal problem, the benefits of  vitamin D supplementation need to be shown.[14,15]
  • 5-HTP (Triptophan): Thought to work like serotonin antidepressants, possibly with less side effects. [16]
  • Vitamin B-12 : From [17], homocysteine has been found in the cerebrospinal fluid  of FMS patients, indicating low B-12
  • Capsaicin ; From Cathy Wong, [12] , there is a FMS study validating the use of capsaicin.  Could not find it.

Massage:

There are some indications that massage-myofascial release therapy can improve the quality of life of FMS people [18]. You need a masseur seriously trained in this particular discipline. The technique involves “…Relaxing contracted muscles, increasing circulation and lymphatic drainage, and stimulating the stretch reflex of muscles and overlying fascia…” (Wikipedia) .

The “Trigger Point Therapy Workbook” [19], though not a book on massage, is a good introduction to the myofascial concepts and an all around  resource for FMS patients.

Mind Body techniques and Tai-Chi:

Last , but not least, Tai-Chi [20] and Mind Body techniques [21] have been shown to be of help against FMS. Both claim some success. Interestingly the Mind Body study’s cohort were all women, but the Tai-Chi study did not mention gender. [21] claims benefit in  “coping with pain, anxiety, depression and somatic complaints” as well as sustainability of the benefits 3 years later…

The Tai-Chi claims [20] are broad :”…components may influence neuroendocrine and immune function as well as neurochemical and analgesic pathways that lead to enhanced physical, psychological, and psychosocial well-being and overall quality of life in patients with fibromyalgia…”

Hope this helps,
