So a few years ago I got a regular spot/zit on my back. It was red and hurt to touch. It didn't have a proper head or anything so I couldnt pop it and after it went down a bit it just kinda stayed there.

I should add that I have a lot of bacne (thanks Dad) so this spot I have doesn't really look out of place

It's only mildy inflated off my back and in fact recently it's actually gone down in size quite a bit

I remember my doctor saying actually few years ago with stuff like that watch to see if it increases in size or change color. But that was then.

I think I'm just concerned. But I get spots all the time. Just not on my face
