A member asked:

Hard lump on back of neck or spine. not moveable. tender to touch. what could this be?

A doctor has provided 1 answer

Infected cyst??: Sounds like you might have had a sebaceous cyst which got infected, hence it is harder and tender now. These are benign swellings in the skin occurring near a hair. See your doc/surgeon about it for proper DX and treatment.
