Hi. I really want to know what this is! It's been there for years, and I've noticed it seems to be getting bigger. It's an area under my right ear and tucked behind my jaw joint, and sometimes it hurts. I can sorta shift it around but it makes weird grinding noises. I have TMJ, but I don't know if it's relevant. I've asked several doctors and a couple of dentists and family members, but they all brush it off. I'm only worried because it seems to be getting bigger and it's making weird noises in my ear that sound a lot like irregular heartbeats. Mostly at night. And I don't even have to be touching it for it to make this noise. And don't give me some weird alien bullshit. Please. Thanks in advance for your help!
