The first doctor told me if the gyno found nothing they would assume it IBS. There is not test for IBS, you just prove it is nothing else. This involves changing diet, logging the type and frequency of bowel movements, avoiding foods that trigger, avoiding stress (ya right), and occasionally bad bouts that require pain meds.
The gyno in office didn't think it was anything. Said she could order another ultrasound with her staff that are very focused in these areas. We said yes. She gave me plenty of meds. Found that I needed a hystorectomy.
I had surgery on 7/13. Feeling much better now. Still not 100% but better than I have been since the end of May.
Moral of the story. Modern Medicine likes to say a lot of female symptoms are PMS or Menopause...it makes it easy. Follow you heart and gut. If you think something is not right, keep finding another doctor to confirm or find out what it really is.
