I was officially diagnosed about 11 months ago and I have followed the gluten-free diet since that time. I have known that I have food issues for 30 years. It was 30 years ago that I developed debilitating wrist pain, symmetrical, like with rheumatoid arthritis. An acupuncture Dr. told me he thought I had food allergies. I did the elimination diet and determined that I had an issue with wheat. The wrist pain (and a bunch of other less debilitating pain) went away dramatically--the improvement was just unbelievable and I could do things again. My hands had become useless, and they completely recovered in probably a few weeks. Other pain in various locations became dramatically better as well. Several months later, I reintroduced wheat, and did not have a return of symptoms. The muscle aches, arthritis like symptoms, have not been much of an issue for me over the last 30 years. But, I developed nasal polyps and asthma. I finally decided to get a blood test because of nagging digestive complaints, the breathing, and knowing that I have a history of some issues with wheat. Blood test was clearly positive, and follow-up biopsy was positive. I have been on a gluten free diet for 11 months. My previous wheat free diet was probably not completely gluten free. I feel much better although I continue to take asthma and sinus medication. In answer to your question, I probably would have been considered to have fibromyalgia 30 years ago, but i don't think there was much talk about fibro then.
