A week ago I started having T. I was in P.E class when suddenly I get hit in the ear with a ball. Later that day I start hearing the ringing. A few days later I see a ENT doctor who says there is nothing wrong with my ear then I get my ear checked by my audiologist who says nothing is wrong with my hearing. I feel as if the hearing test was not very accurate since I do hear a difference in sound in one of my ears. Can tinnitus interfere with hearing because that is what my audiologist said? Also could this ringing be from a concussion because that is what my doctors told me or the noise the ball made when it hit my ear
