Hi Doctor, I am a female, aged 28. I used to get nerve pull meaning, a sharp pain in the calf muscle area (backside of lower part) on one leg . I got nerve pulling in the past, when I was tensed or think too much (I get them in the night) or when I walk on a cold floor. Please correct me, if this is called as nerve pull. But , yesterday, I got this sharp pain in the night. I am sure, i was not tensed and I in fact took good long sleep. It usually lasts for less than 60 seconds (Not a accurate time). I recently checked my blood, I have normal HB, thyroid level is 0.04 level more. What are the things to be done by me, so that I don t get this pain.
