A friend of mine thought it would be fun to crack a noise bag (those shits that you throw and produce a lot of noise) next to my right ear. Now I feel like there's "fog" in my ear and I can't hear clearly. I used the video I linked to see how uneven my hearing is between my left and right ears. In the video I could go up to ~15kHz just fine, but my right ear couldn't listen beyond 7,4kHz.

It's been 4-5 days since it happened and I see no self-healing going on so I'll visit the doc this week. How serious do you think it might be?
