This is my fist time on the message board but I have a question. I was diagnosed with FM December, 2005 so I am fairly new to this disease. Does anyone know if it is very common to also have tendonitis also? I was diagnosed with tendonitis in my right ankle 3 weeks ago and now I am also having trouble with my left wrist and thumb, right wrist, thumb and little finger. I'm still trying to understand this crazy disease. It sure is frustating.
