question: Hi, I have a small, squishy lump on the underside of my right butt cheek. It s no bigger around than the tip of my pinkie finger, not painful, and only noticed it when shaving today. It s not red, there s no white head on it, so I don t think it was caused from shaving. I have no history of cysts or abscesses, and was wondering if something like this could be caused by pressure? I rode a stationary bike for the first time in a long time and went 30 minutes even thought it was quite uncomfortable right in that area (I have a flat, bony butt) I ve never had anything like this before.
