you need to have a medical professional examine your ears. this is really the only way to get an accurate diagnosis. this could be as simple as a wax impaction or a bit more challenging like middle ear fluid. your ears are important so get examined. an urgent care facility is fine.
slept on ear and now i can't hear. two days ago i slept on my left ear and when i woke up i had a muffled ear. i can barely hear anything and i have the ringing sensation. when i push the little thing that covers the ear canal back i feel a gust of air coming out. when i burp i also feel the gust of air yesterday it got better after messing with my ear a bit but today i fell asleep on my left ear and now i think it got worse.
