Is exercise recommended for people woth FM? I tend to feel better when exercising. Joints and everything feel somewhat better. For instance, I can sit with crossed legs for longer periods of time. Only thing is, my preferred method of exercise is jogging and among other mysterious symptoms I have been experiencing over the past few years that I never had before, I now experience frequent cramps while running. Though my joints do feel better, is an FM person just screwing up her body even more in the long run through high-impact exercise such as jogging, more so than a non-FM person? I have not been able to jog for the past few months due to recovering from an ankle injury but have been intending to start back up again any day now.
