First and foremost I am planning to see a doctor as soon as possible. I'm trying to avoid going to urgent care since it's not causing any pain, but I'm planning to make an appointment once the weekend is over. I'm just trying to calm my nerves since I've been having the worst anxiety since last night. Anyway, my roommate recently had to go to the doctor for a PC. I've never heard of this before and after some research I thought that maybe this lump I've had for quite some time, could be the same. I want to say it's been there for a few years. Never causing me any pain or worry. It's been the same size for as long as I can remember. It's possible it may have grown a little but not by much since I can't really tell any difference. No redness (except for recently since I've been messing with it while trying to figure out what it is). I have not tried to pop it and for the most part I've left it alone. I've taken a few pictures. http://imgur.com/2K0AUVt http://imgur.com/gwXPYpe http://imgur.com/3gaj6H6 As you can see, the bump is not by my tailbone but actually closer to my anus on my right cheek. That's the only reason I've suspected it not being a PC since there are no holes, cysts or anything near my tailbone. There is a little redness at the top of my cleft but this could be due to sweating or just needing a good cleaning. No itching, or pain in that area as well. I suppose I'm just looking for an opinion. Granted I will still get a doctor's opinion, but I've also been told it could be a sebaceous cyst or just a fatty deposit. I'm just suffering from a lot of anxieties and this is ruining my weekend. I just don't want to go into the doctor's office with no hope at all. I'm already feeling a little hopeless. Any advice or opinions is very appreciated.
