I have a bump on my neck-shoulder. since last summer/fall. it started out as the same feeling as a pimple on my back, except it had no color. currently it is still there. it is hard. but it has not grown. it is just "there". skin colored. and not painful. just annoying when i rub my shoulder/neck and feel it.

when asking my grandmother (ex military nurse) what it was, she claimed it was a Blind Boil.
she recommended putting hot cloths on it.

i tried that, but no result. any ideas?
