This is becoming a growing concern. Every now and then my left ear will go almost completely deaf. Sometimes it lasts for a couple of hours, and sometimes for a couple of days. I think it might be caused by built up wax, a sinus conjestion, or both. The odd thing is, when i clean my ears, my right ear always has more wax that comes out, but the wax from the left ear is harder and darker (the right ear normally has a good consistent yellow texture). It has been this way for as long as i can remember. I always wear ear plugs, good ones too. But my often my deafness rears its ugly silence after i wear my plugs for a long set. Perhaps i'm pushing wax deeper in my ear, or triggering more wax to form, i dunno. what should i do?
