<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am a slim 33 year old with no children. Last year and this year I experienced heavy bloating which after a scan was noted both times as being ovarian cysts and possible endometriosis. However, both times after a couple of months my bloating has subsided. Although I feel normal now outside of my periods, during my last two periods I have experienced crazy bloating, quite a bit of pain and have noticed clotting in my bleeding. Should I be concerned? Many thanks  <response>: Hi welcome to Chat Doctor. I have gone through your question. Clotting pain while menstruating suggest most possibly endometriosis. Endometriosis should be treated medicallyconservative method and surgically depends on severity. Conservative method is painkiller NSAIDs. Naproxen, Hormonal contraceptives. Surgical treatment, Conservative surgery to preserve uterus and ovaries if planning for pregnancy. Hysterectomy if endometriosis is severe. Hope I have answered your question. Would be happy to help you further. Take care.
