when i'm on my feet for extended periods of time or over exercise i get horrific craps in my knees and calves. i always reach for the heating pad or heat the rice bag up, but talking to my co-workers about it they suggested that i put ice on it. one even said that her doctor told her to put ice hers if they cramp. i would think that ice would keep the muscle tight and continue to cause pain. though it takes awhile for the pain to stop i've always thought that heat would relax the muscle and ease the pain, even make it easier to stretch to help stop it.
is it a personal choice? do you perfer ice or heat for cramping muscles? what has your doctor suggested?
