Hi. I m a 34 yr old female. For a few years I ve had a bump behind my right ear. When I get nervous or bored I ve noticed I try to pop it. It does cause some discomfort but nothing to bad. Lately white hard pasty substance comes out of it. Tonight I tried to pop it and it started to bleed a little. There was no smells when the white substance came out. What could this be?
Hello. Nothing urgent. That is probably lymph node. You should be checked is there maybe an ongoing latent infection (systemic or local). Also, you can do cytological function of "bump" to get real description of substance inside bump. All the best.
