Sounds a little like fissures besides the bump (skin tag) that you see, I have multiple and large skin tags but they didn't/don't feel like what you're describing except when I have fissures as well...until you're able to see your doc, do sitz bathes with epsom salts and pat dry, then gently rub some extra virgine olive oil on the area.
This would be your anus that you are having issues with, your rectom is the area just inside the anus, then your colon, ect.
My bum is broken....there's a big crack down the middle of it! LOL :)
