I'm sorry to all those suffering with FM-- it's an unusual disease that is difficult to diagnose and often brushed off as not real by many health professionals.
I do not have FM but I have learned a little about it in my studies. There is good research showing that regular moderate-intensity exercise is a huge part of successfully managing FM. This includes aerobic conditioning and strengthening. I know this sounds like it may be totally out of the question for some of you, but it really is doable! Having someone to help manage the journey and of course going slow and being patient with yourself are imperative.
