| Lump under Skin on Back
I hope that I picked the correct board for this, I apologize if I didn't.
Just recently I've been bothered by a very small lump right under the skin on my upper back just below my left shoulder. It is a hard lump, and I BELIEVE that it is not attached to my back (I think that I am able to pull it away if I grab the skin). It does not hurt at all, and I have no clue what it could possibly be.
I thought it potentially could be acne, but as far as I've heard, blind pimples are painful. Does anyone have any idea on what this could possibly be? I appreciate and thank you for any tips/advice/responses in advance!
