I have been getting a shap pain in my left leg near my knee. At first i thought it was just a cramp, and may still be, but now I am wondering if it is a nerve. It is a quick, sharp pain that goes away in seconds. Feels like someone hit me with voltage and it is only in a spot that is about a quarter size. There is no real ryhme or reason behind it. It has been happening for about 2 weeks now but it is starting to happen more often and the pain is worse now then when it first happened. Any ideas, thanks?
