Hello all.

About 2 months ago, I noticed a strange looking bump on my lower back just above my anus. I disregarded it for a while. Now, it's still not gone.

It has a pearly, almost wet texture, and is skin coloured around the outside, but a bit red in the center. Every morning when I wake up it feels a little hard, but by the afternoon, it is back to what I described above. I'm not really sure what it is, but now it's starting to worry me.

Any ideas?

Thanks.
