wish i could help JJ, woke the other morning and had cramp in both feet, suggest perhaps its what kind of sleep you are getting, mine isn't remotely restful.
oh I know that Em and Mamy - my sleep is not at all restful but don't think I should have the pain I have in the morning. Sometimes feel like I have run a marathon.
I wake up quite often with cramps in my legs, sometimes feet. I find it happens less often if I have had an active day, especially if I have been for a walk.
I think its not moving that causes the pain. I ache less when i haven't slept well....and cramp, I find has nothing to do with rest or not but more about body chemistry
Been waking up with aches and pains for quite a few years now & gradually getting worse. Takes me an hour to get moving properly in a morning. Arthritis?
PS. I think I saw a recommendation to do some exercises on the bed before actually getting up.
