Today is the second time in the past month I've woken up and my ears are "popped" or unpopped... whatever you want to call it. It's like that sensation on a plane but very mild. I tried popping them/yawning and it doesn't fix. It feels like my head is vibrating when I hear bass from my music (pretty cool feeling actually ) Is this something normal? could it be from weather changes/barometric pressure or some bullshit like that or should I see a doctor? Or could it be related to heavy deadlifting/squatting?
