Proctology question? Please?

So recently I was sick and I was pooping a lot, one of these times I found blood in my stool and I figured it was because I cut my while moving a bowel. Now I have this squishy lump with a black dot right next to the opening of my . It is very painful to the touch and is painful to sit down or walk. What is this? And what should I do???? Thanks for the help
