I got something growing in my anus/rectum and perhaps colon. I don't know what I have, but something is going on down there, and I need to see a doctor. sometimes, I get weird feelings when I pee, and the area around my rectum hurts randomly.

I hope it's a simple bacteria infection, and not something like colon cancer or something
it started two months ago

when I touch my rectum, I feel bumps, like swollen glands or something
