I don't know if this is still active, but I have the exact same thing as you. I'm still in high school, and a few months ago I noticed when I was watching TV my left ear felt like it was throbbing, kind of like a "thump" sound. I cant describe it as a heartbeat because it doesn't have that sort of rhythm, its more of a rhythm associated with the way that people talk, as if its a response to that sound. It doesn't necessarily 'hurt', but it makes my eyes water and it feels like a mild pain and an extreme nuisance. I also noticed it really only occurs in response to male voices, which does make some classes difficult. I tried cleaning out my ears with a proper kit and that did not change anything. What I find odd is that it is not consistent, so this doesn't always occur when male voices are around regardless of volume. I have never had any issue with sounds before, I have not had any surgery or severe head trauma either. I had a mild head injury last year but I don't see a connection to that in terms of when my symptoms started. I do have depression, anxiety, ADHD, and I am on medication for those, but again I don't see a correlation based on onset of symptoms. The only correlation I could see is recent stressful events. If you have any answers on this or just some things you've noticed, I would love to hear them.
