Took my 13yr old son to Dr today, he has a hard lump behind left ear. After an exam, Dr said not a lumph node, the lump doesn't move, about the size of a larger jelly bean and is sore when touched or pushed on. Not sure if pain comes from pushing on the lump or from the pressure of the lump against his bone when pushing. No sign of infection in ear or around/on lump itself. no sign of bite etc..... not sure how long it's been there, just noticed last night.
Have been referred to an ENT next week, but just trying to get any idea what it may be.
