I've been having lower left abdominal pain for a year now. I've been to many doctors, who first suggested ovarian cysts/endometriosis, but have recently suggested IBS. The pain is mostly on the left side, sometimes on the right, with pain radiating down legs and in my lower back. It has gotten substantially worse in the last 3 months. On Friday I woke up in the middle of the night with waves of very intense stomach pain. They lasted about 30 seconds, with the pain beginning mildly and increasing until it was unbearable. Each wave came back after about a minute, and was accompanied by sweating/feeling faint. I was finally able to have a small bowel movement, and the pain went away. My stomach has been extremely sore for the last two days.I should say that I don't have any diarrhea and constipation--just abdominal pain. When I was finally referred to a GI, she said it might be constipation, but I go 1-2 times a day. Does this sound like IBS? I would love your thoughts/ideas.
