[|Human|] Hi, I had anal sex with my boyfriend a few days ago and have now noticed a small, hard lump near the entrance to my anus . I am very concerned about this. Before having anal intercourse my anus was itchy and sometimes there was a little red blood on the toilet paper but I think it was because I wiped too hard. It is now hurting when I sit down and I feel like there is a mass in my anus. I am so worried that it is something like Anal Cancer . I do suffer from IBS though by the way. Please Help!
[|AI|]  It is highly unlikely to be anal cancer by the picture that you have given. It is more likely to be a localized infection which got aggravated by the intercourse. I would suggest you to take a tub full of warm water, put a tablet of potassium permanganate in it and sit in the tub for 15 minutes thrice daily. Also take Tab ciprofloxacin 500 mg twice daily and apply ointment nitroglycerin (just a small amount) at the anal opening before passing stools. Avoid constipation and anal intercourse. If the symptoms don't get relieved in a week, show yourself to a surgeon.
