Okay, this is going to be a strange question. This has only ever happened to me once before.
My husband and I were having sex last night, when I got a horrible sharp pain on my left side. He had my legs propped up on his shoulders. Everything was fine before that happened. It's now over 12 hours later and I still feel like someone put a hand full of razor blades up there and then stepped on me. We have sex all the time. I just can't understand what happened. I don't know if I should wait it out, or go to the ER or my doctor. What are the causes of pain like this?
