So about 10 days ago I removed my last amalgamate. I suppose it has started few days after but I wasn't paying much attention since I am used to occasional spikes. But last Saturday I went to a concert, nothing super loud, felt really good and I always wear ear plugs. Although after I left it was really high pitch in my head - again I didn't pay attention since occasional spikes happen. But last two nights I could not sleep very well. It freaks me out that I have done some permanent damage to my poor ears. Any advises?
