Symptoms of endometriosis include pelvic pain (usually before menstruation but sometimes during intercourse,urination or defecation), sometimes diarrhea or constipation,irregular or heavy menstrual bleeding,sometimes blood in the urine and inability to conceive.
Although ultrasound is useful in diagnosing endometriosis, but still cannot definitively diagnose endometriosis.Laproscopy is the only accurate way of diagnosing endometriosis.Treatment involves NSAID pain killers,GnRH analogs,oral contraceptive pills,progestins and surgery.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
