Yup I did the hearing test and typmanometry test. They all come back as fine. Actually I didn't notice at first when it first started. Only a few days later, I happen to notice my ear has been twitching for some days. I do wear earphones pretty often. Now I don't wear them anymore ever since I got it. That period I was more stressed out than usual too. Other than that , nth much difference.Have you done a hearing test?
I'm also curious, would you mind describing how it all started? Like, on the day you got it, what were you doing, were you wearing headphones, etc.?
