i have a throbbing pain in my left calf. every night before sleep it gets really bad and it just throbs. its been like this for nearly 9 months and i went to the doctor once (6 months ago) and i was given a cream to use on it, i used it all but the pains stoped for only about a month and came back. can someone please tell me what it might be from? the pains only come when im cold most of the time, and at night sometimes when im lieing in my bed it hurts really really bad and just keeps throbing. if i sit in an uncomfortable position, i get pins and needles very fast in my left calf compared to my right, what might be the problem?
