I have a lump at the base of my neck, on the right side, where my shoulder is. The size of a small plum. It doesnt hurt, but makes my shoulder and neck feel tight and restricted in movement. The lump is semi hard, I can get four fingers around the lump, it doesnt really move when squeezed.
HI. This may be a sebaceous cyst or a lipoma. Get this checked by a Surgeon and the best way to get sure treatment is its excision. The disease goes away, and you get a confirmed diagnosis.
