My daughter is 16, not sexually active, very athletic and in good health. Approx 2 1/2 months ago she started complaining of "cramps", I brushed it off thinking menstrual cramps. After her period was over she continued to complain of cramps and stated they were getting worse. When her period came the following month she was in severe pain, (lower abdomen/pelvic area) period was heavy, lasted 10 days, and she complained of increased urination. I made an appt with gyn and she ordered urinalysis and ultrasound (I suspected a cyst on her ovary). Was told that both tests were normal. My daughter continued to complain of pain stating it was getting worse. I took her to another dr who ordered CT scan of abd adn pelvis. This came back showing fluid in pelvic area. Dr referred us to GI specialist who performed colonoscopy. To make an extremely long story short. My daughter has been complaining of this lower abd pain for almost 3 months now. She says is ranges to mild cramping to sever stabbing pain and it is there on a daily basis. She has increased urination, decreased appetite, fever off and on, bouts of nausea, abnormal periods (last one was 2 weeks late, lasted over 10 days, passing lg clots). If she had a cyst on her ovary wouldn't it have shown on the US and CT scan? If it ruptured causing the fluid that was shown on CT scan wouldn't the pain have gone away? She is going through test after test and everything is coming back 'normal' I'm at a loss as to what to do. She has tried Tylenol, ibuprofen, Bentyl, levsin, warm cloths to abdomen. Nothing is helping. Can you offer some insight? Thank you in advance.
