<s>[INST] 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 [/INST] Hi welcome to Chat Doctor. I have gone through your question. Clotting pain while menstruating suggest most possibly endometriosis. Endometriosis should be treated medically(conservative 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. </s>
