Hello-
Today I noticed a lump behind my right ear. Not on my ear, on my head. It is alittle tender, I'm almost positive it hasnt been developing gradually because I would have noticed it before... it honestly seems to just have popped up overnight. Atfirst I thought it was due to a pimple but with further inspection there is nothing on the skin. I read up on some sites, and they said it could be one of my lymph nodes swelling due to infection. I have my cartilaged pierced, and for the past week or two it has been infected. I've had the piercing done for 2 1/2 years now but lately its been acting up and getting infected. My question is do you think that the bump could be from something as small as a piercing infection? I'm kind of hoping it is and not something more serious... I'm really worried and the bad part is I hate going to the doctors.

Any advice is appreciated. Thank you!
