Okaaaay, so basically my problem is.. i find i'm constipated, and there seems to be a swollen gray bump on the side of my anus, that somewhat extends inside.. I'm 21 years old, just wondering what it could possibly be
Welcome to A2A, twistoffate9991. It sounds like a haemorrhoid. That would be typical if you are constipated and have to strain a lot.
You probably need more fibre in your diet - wholemeal bread, lots of vegetables, and whole fruit (not juice).
