I am 27 years old and have had reoccuring bumps on the top part of my butt crease. It is always just one and has ranged from feeling like a pea to the diameter of a golf ball. If I go to look at it I normally can't see it unless I feel the bump, now there is a slight pink color to the area where the bump is. Sometimes it goes away in a few days... sometimes over a week. There has never been any pus or blood at all, just an uncomfortable sitting problem. I have no idea if it is a cyst since most people have pus or blood. I read somewhere that flare ups occur when stressed or bad posture. I am currently 3 months pregnant and surgery isn't an option right now. Anyone know if this would still be a pilondial cyst, or an anal fissure, or something else??
