I had sharp pains in the same area last month along with headaches and dizziness so bad I couldn't stand for more than a few seconds. I went to the doctor and they thought I had appendicitis or an ovarian cyst, but they said with the symptoms that it was more likely to be appendicitis. It ended up being an ovarian cyst. I had to have ultrasounds done to confirm it. I would say get it checked out because if it is appendicitis it's nothing to wait around for, it can be very serious. Or, it may be a cyst like I have or something else. I actually wish mine had been appendicitis because it would be out and gone but instead I get recurring pain from the cyst during that special time of the month ... and I'm actually not feeling too snazzy right now because of it. It really, really sucks!
