Hello, doctor, my name is Richard Lemen, I m 18 years old, and I m roughly 160 pounds. I have a bit of a concern, with a scratch, or what even looks like a puncture wound, or hole, right where my coccyx is. It burns, and stings, whenever I pass gas, and sit down, and I m afraid to use the bathroom, because my anus burns, whenever I attempt to do so. It seems a bit swollen, and it s definitely red. It s been like this for 2-3 days now, and it hasn t gotten worse, or better, but I noticed, when I used the bathroom those 2-3 days ago, a piece of skin, of clump of blood came off, and it hurt, after I wiped, and I thought nothing of it. When I saw it, I stopped sitting down, and kept it clean, as mush as I could. I d greatly appreciate your help, thanks.
