Hello! I'm kind of embarrassed to go to a walk-in with this concern so I thought I'd ask here. For the past week, I've had a bump to the left of my anus. Just yesterday it became very large and very painful. It's hard and about 2 inches in diameter. It woke me up last night since I'm kind of putting pressure on it no matter which way I sleep, so I took a Tylenol in hopes of decreasing the pain. Is this just a simple pimple I can wait out?
