I think I was recently bitten on my shoulder by some sort of bug. I quickly removed something from my shoulder without getting a look at what it was. I'm not sure if it was a tick, etc. Anyway, after that I noticed there was a bump where the bug was removed. The bump remained for a few days, and slowly disappeared however a dark spot still remains there. Now a few more raised bumps have been developing near that area on my upper back and shoulders, I even found one on the side of my neck. When I pick at them they sometimes flake in the center and are surrounded by a darker section.
Any idea what this is? Should get it checked out before it worsens or will it go away on its own?
