Lately, I'm being woken at all sorts of odd hours by agonising, horrible cramp in my calf muscles. Occasionally in my feet too. It's so painful and sudden that it wakes me up and I have to get out of bed to walk around to get rid of the cramp. Understandably, this is not endearing me to my husband. It's also knackering me as it takes ages to get back to sleep. :-( Anyone else had this problem or know what might be causing it? Feel it's a tad too trivial to bother the doctor with. Thanks in advance.
