Fibromyalgia is not a Rheumatological Disease

Thanks to Jacqui for finding this one!

Fibromyalgia Is Not a Rheumatologic Disease Anymore

Think of your last patient with difficult-to-treat fibromyalgia: Aren't they all? Did you refer that person to a rheumatologist?

Since the 1950s, when it was first described by Dr. Graham, "fibrositis" or fibromyalgia was thought to be a rheumatologic disorder because it was characterized by musculoskeletal pain similar to other rheumatologic diseases.[1]

In 1990, The American College of Rheumatology established diagnostic criteria based on the scoring of 18 potential tender points.[2] It turns out, however, that these tender points have nothing to do with fibromyalgia. Biopsy of the tender points shows no pathologic changes, and numerous studies have not shown any abnormalities in the musculoskeletal tissues that are painful.

Current evidence points to a neurologic disorder of central pain processing.[3] Fibromyalgia patients experience pain differently and have lower pain thresholds compared to normals. Research has demonstrated that various pain-related processes in the brain and spinal cord are abnormal in fibromyalgia.[4] But more work remains to be done.

Market surveys show the number one class of drugs used to treat fibromyalgia is nonsteroidal anti-inflammatory drugs.[5] Since fibromyalgia is not an inflammatory disease, it is not surprising we have a lot of treatment failures.

The pharmaceutical industry knows this, and they are viewing fibromyalgia as the prototypical central pain state. The 2 main drug classes of interest are the dual receptor reuptake inhibitors, like duloxetine or Cymbalta, and the antiepileptic drugs, like pregabalin or Lyrica. In fact, pregabalin has shown enough efficacy, that it is the first and only drug approved by the FDA for the treatment of fibromyalgia.[6]

Therefore, in the future, with new insights and therapies on the horizon, we will no longer need to refer our fibromyalgia patients to the rheumatologist.

That's my opinion. I'm Dr. George Griffing, Professor of Medicine at St. Louis University and Editor-in-Chief of Internal Medicine for eMedicine.

I took enough Advil to give me an ulcer without any relief at all.  Even in prescription doses, and even at higher-than-prescription doses, it did nothing for my pain.  The doctor's response to my complaints of constant pain?  "Take Advil."  This five minutes after telling me to stop taking Advil because it was giving me an ulcer!

As much as your doctor may hate the idea, lean on him to provide a mild narcotic/opiate pain reliever, which is the only thing that works on the neurological pain of CFS/fibro.  Tramadol/Ultram is so mild that it is sold without a prescription in Canada; 50 mg of Tramadol provides me more relief than 1200 mg of Advil.

If your doctor won't provide it, tell him you want a referral to a pain management specialist.  Untreated pain can cause changes in the central nervous system within a day or two, and those changes may be permanent.

Meanwhile, try heat: hot bath, heating pad, ThermaCare wraps.
