I found a pea size to marble size hard lump, above my left shoulder blade, its moves easily around, doesnt hurt.  I had a tick bite last week on my left shoulder.  the bite swelled up got a little liquid inside it and now is scabbed over.  This lump moves like it has no thether... Im scared.
HI. The movable lump is never to be bothered about, and if it is due to sting, it will settle with time. Still consider the possibility of a lipoma... as this is movable. Incidently the bite might have been there only
