In the last three months I developed three lumps around my ear and neck region. I went to a ENT and he said it was unusually large lumps but thought I was fighting an infection. However, I have not been sick or had a noticeable cold in a while. I was given antibiotics and a month later they were still there. Today I had a sharp pain from the one behind my ear (in-between my hair line and ear). I touched it and it was noticeable larger. The lump is the size of a grape cut in half, very hard, and immovable. Should I go to the hospital because it is throbbing or wait for the ENT follow up.
