I was sitting in a cafe chatting to a friend and sudden really intense pain came on - very low on right hand side. Never had anything like it, couldn't actually talk through it. Friend drove me home and was in agony, then after about half an hour it disappeared. I've not had a pain like this before, was very sharp stabbing pain. I was intending to come straight in an call the doctor but it's just gone.
Has anyone experienced anything like this, what could it be?
