Thank you for posting this question. I too have had fibromyalgia pain after I exercise but it usually takes itself anywhere 6 hours or so to hit me. When it does hit me then I'm just wiped out completely like I have the flu and my whole body is just going insane feels like. I have tried different types of exercising like walking and swimming. But with light exercises and found that I just can't do those either. It's almost made me afraid to exercise at all.

I'm unable to give you any words of wisdoms as to why or how to fix it as I still don't know how to myself. But I wish you the best of luck and if you find something out I'd be very interested to hear.

Best wishes
