<s>[INST] Hi, may I answer your health queries right now ?  Please type your query here... I have a lump near my anus that extends up to the gooch. I had unprotected anal sex with my boyfriend about two months ago but it wasnt a sudden swelling, it has been gradual. Every time my boyfriend rubs it during sex it swells up a bit and is a kind of purple colour. However, it doesnt hurt in the slightest. There is no visual cut that I know of and it is the size of a grape. What do you think it may be? [/INST] Hi, dairy have gone through your question. I can understand your concern. You may have some hemorrhoid (piles).  You should go for examination.  Take plenty of water and high fiber diet.  Avoid constipation. Permanent treatment is surgery.  Consult your doctor and take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health. </s>
