I got slapped on the face pretty hard about 5 days ago, and my ear is swollen and I hear ringing in my ears, and I can't hear very clearly. I consulted a doctor and they said there is no damage to my eardrum, but my ear is very red, so it is swollen. I got ear drops, and I've been taking them for a day but I still hear ringing and my hearing is still a bit blocked. Also, I had pain in my ear when I got slapped, but it went away after a day, but when I put ear drops I get Severe pain in my ear from 20 min to sometimes a few hours, and after it subsides, my ear starts to itch, why is that?
