There are many different attitudes and thoughts concerning people with Fibromyalgia and even the disorder itself. At this point many people do not consider it an autoimmune disease. There are also those who do not believe Fibro exists.
Then there are the people who do believe it exists, but have no idea what to do about it or how to explain it. Some medical professionals and lay people consider Fibromyalgia to be a psychiatric issue.
There are many doctors who refuse to take patients who claim to have the disease. The question which can not be answered is why other medical doctors would actively treat people who claim they have it.
The good news is that not only is there a group of doctors who treat people with Fibro, but they have hundreds of patients. Their patients have similar symptoms in vastly different personal situations.
Logically it would be extremely difficult for that many people to study a textbook and successfully lie about it. Lie many times to many people. Most people who find a doctor who treats Fibromyalgia have told there story to many medical professionals before they got there.
