I am an English teacher and I developed tinnitus after a concussion. The ringing had subsided quite a bit until recently when I returned to the USA from Japan and took a Customer Service Rep job. I have to wear a headset covering one ear, and today was the worst. I left the centre and my ear felt stopped up and the tinnitus was as bad as ever. I want to quit the job, but will have to find a new one first. Tomorrow I will try to stuff some tissue in my ear when wearing the headset, hoping that I can still hear the customer. Having the tinnitus come back so strong after being mild for so long is really scary. Any thoughts? Thank you!
