<s>[INST] a week before christmas i had severe lower back pain with severe pain waistline below belly button... i couldnt sit and finally had to go to the bathroom...there i was in so much pain(embarrassed but) i was wiping and something slid out onto my hand which was a huge blood clot. almost instantly the pain somewhat subsided. can you tell me what this may have been? [/INST] Hi, The symptoms you have been describing are classical of an external hemorrhoid. You need to consult with a general surgeon and get it looked at. There are a few preventive measures you need to take meanwhile like increasing more fiber in your diet. The more fiber you take the lesser will the inflammation in the bowel be, and it is also known to decrease the itching in the perineal area. Also, you can have site baths more frequently. There are commercially available tubs for that purpose which will help in alleviating the pain. Hope this has answered your question. </s>
