I have had horrible pains in my calfs for a while now. Due to ibs my diet is fairly restrictive but I do take take sufficient supplements. I have horrible calv and pain in my knees, also sometimes spreads to the feet, it is really a fatigue of the entire body but the pain in my calves is horrid. It gets worse with exercise and better immediatly as I rest. I heard this could be a potassium defficiency. hehe haven't been eating my bananas since ibs-c hit about a year ago.. any help would be appreciated.
