I can remember when fibromyalgia landed under the umbrella of rheumatology. I suspect this was because of the muscle pain involved; however, FM is not a joint disease. Quite frankly, I am not sure they were sure where to put us. At any rate, this is where we landed.
Since this classification was made research has exploded in the area of neurology. Most experts, including rheumatologists that treat FM, believe fibromyalgia is due to an upset in neurotransmission in the brain. Because of this, possibly the neurologist would be the person to see. However, they too are not well versed in the presence of myofascial trigger points as peripheral pain generators in FM or understand the myofascial involvement.
So for now, if you have a rheumatologist or neurologist that understands and is current with the research on FM, you are in the right place.
