I haven't drank in such a long time. Last night I went out with friends and drank for hours on end. Now, I'm home, and my butt is killing me. There is a large painful bump that's towards the end of my butt cheek. When I track down how long it is, it goes from my butt cheek to my anus. It's very painful, I keep waking up from my sleep.
What can it be?
