Is there something wrong with me? Whenever I have to deal with period cramps, when they get particularly painful a throbbing dull ache starts in my left pelvic area/ leg joint area. It spreads through the inner side of my leg from the pelvic area to my ankle. It doesn't affect my ability to move my leg but it's uncomfortable. I always figured that it was due to there being a lot of nerves in the pelvic area. However, I don't know if this is correct. Does anyone know what it might be and if it's a severe problem?
