Hi there, I m a 25 year-old female with persistent lower abdominal pain. It s usually on the left although some times its on the right. Its crampy pain that interferes with work. A week ago, the clinic prescribed T3s, which have helped the pain to a manageable level but not eliminated it yet. It may be related to possible PMDD. Sporatically, my bowel movements also involve little fluid filled mucus looking sacs with blood. I have had a few of these in the last week, which may or may not be related to the lower abdominal pain. Do you have any ideas?
