I've been having sharp knife like vaginal pains since about 2001. I have been to every kind of doctor. I've had steroid shots in that area of the vagina (only on the left side). That didn't help. The pains are only on the left side of the vagina. Not in the rectum..They're pretty consistent throuh-out the day, every day. After I urinate, they seem to intensify, however, urinating doesn't always bring them on.
