I am a sign language interepreter and I am noticing that I am able to hear but not able to identify words. especially accroynms, and words that rhym like cat, bat, hat..they all sound the same. I have a hard time hearing on the phone even with people that I talk with frequencly and have to use ear phones when I do talk on the phone. There can be no background noise or I can not understand anything. In person, is normally fine. Should I bother going to the doctor or is this just an annoying issue?
