Since about last year, I've noticed a lump on my shoulder, a bit less than a centimeter in diameter. It doesn't look like it's growing. The growth is underneath my skin and doesn't hurt at all. I can move it around as well when my deltoids aren't stretched.
Ummm, probably not. I have almost the same thing on my temple. I went to the doctor, and they said it was just a lump of tissue. It's completely harmless, but if you want it taken out, then they can do surgery.
