[|Human|] I just noticed a small swollen area on the inside of my anus. It seems like it s filled with something pus or blood like. I ve been messing with it and it s gotten a little bigger. It hurts mainly when I cough or sneeze and when my anus contracts. I had sex the night before with a condom and it was not anal sex, but vaginal. I m concerned what this may be. Is it an std or is it something like a hemorrhoid or anal abscess? Please help
[|AI|]  Helots swelling may be :1 Fissure in anus .2 Hemorrhoids 3 Abscess. But merely according to this history it is very difficult to establish any diagnosis. Physical inspection is important, so in my opinion consult a physician and get his opinion. In my opinion this is not an STD (protected sex vaginal) . Since this is very painful so may be anal fissure. Good luck. You can use lidocaine cream for local application for pain relief.
