Hi lost_angel, sorry to hear that you are having such a bad time. I just got better from a major ear block episode! Couldn't hear anything clearly and the pressure was bad, not forgetting the ringing.
Is it the first time that you have these symptoms? Yawning and doing the normal swallowing didn't help me, only when the ear decides to pop back and then I'm able to hear abit better. Maybe it might be all the pressure that's causing you to feel the tightness. Do you think so? Do you hear the ringing even when you are in a crowded place? Since your ears are blocked, the fluid in your ears might not be able to change with your movement quickly, thus affecting your balance.
Are there any pain in the ears? If there's, there might be infection. Have you gone to see a doctor? Hope you feel better soon!!
