Hello, I would like to know if you could tell why sometimes both my legs hurt so bad. This does not happen to me often, but when it does it truly bothers me to the point that I can not sleep with out taking any kind of pain medication such as tylenol or advil. I have mentioned this to my doctor in the past. However, when I have asked this question, my legs are not hurting. Therefore, she has not been able to give me a good answer.
