What causes of hand and foot cramps?

This problem can be caused by an under active thyroid. However cramping can also be the result of mineral and salts deficiency, however what ever the cause it may be wise to consult a physician if the problem persists. Many people would put this down to a problem with arthritis, however that would not be consistent with an arthict problem as Arthritis is a joint disease which can attack muscle but will not cause cramping.

most likely arthritis. there are water therapy classes, check out the arthritis foundation. focuses on movement of all joints with minimal resistance created by warm water. the water must be 86 degrees. check out pools near you as well. the arthritis instructor could be of some help. a doctors opinion would be good as well.

Your questions wasn't specific enough but i get that sometimes. I'll stretch my legs and straighten them as much as possible then my toes start to cramp up and i cant move them any more.. TEMPORARILY though. for maybe 10-30 seconds and man does it hurt. I'm guessing its your muscle being stretched farther then it is used to or then it can and it starts to stop working to get you to relax.
