| | Private area muscle pain. Right side
For the last two weeks I've been having pain in my rectal area/butt cheek.
The pain is constant, as if it is bruised, and is especially sharp in the morning, or when I sit down. I've felt a knot (about the size of half a thumb) on one side of the anal opening, though I'm not sure if that's a really tense muscle, or something else. It doesn't hurt on the other side. I'm not currently sexually active so that can't be a reason. The lump doesn't show, I can only feel it if I poke the area.
Does anyone know what this might be?
