I've noticed a small bump on my back right at my shoulder blade. My boyfriend was rubbing my back a few weeks ago and he noticed it too, so then he squeezed it and a white film came out, not a pus but a dry white film. He squeezed it harder and well more came out. After that lil session the bump was almost not there. But then a few days maybe a week it was back so we did it again. I haven't seen a dr. for this yet because I think it is just a clogged pore, and he says I should see one. So anyone have any idea what it is?
