Hi, this is super awkward for me to talk about

Patient: Hi, this is super awkward for me to talk about so I’m happy I can do it online. Yesterday, I noticed a pain in my butt? literally. Around the opening of my anus, slightly inside, there’s a hard, pea-sized bump. I tried to look at it and it looks as though it’s a little bit white in colour. It’s incredibly painful when I have to poo and to wipe afterward. I really don’t want to go to a doctor in person if at all possible. What could be wrong?
