Hello doctor,
Yes, the current problem started immediately after the loud cleaning of my left ear. I had both ears cleaned right before having the audiogram that I sent you. I had this done to see if hearing aids would help. There are no symptoms other than dullness and the 1Khz ringing that happens when I am around white noise like a river or an electric fan. I will contact the audiologist regarding an electrocochleography. No, I do not wear hearing protection when engineering. I just started to prednisone an hour ago. I will ask about direct ear injections. I do not have diabetes. I do have a GERD.
