Thanks for you post James. I was interested to hear about your pitch shift. Mine seems to up about a semitone though, not down (maybe because it's my left ear
). I'm going for an MRI next week and I'm currently on a short course of steroids, which appears to be the standard treatment. Reports say this only affects about 1 in 5000 people, but it may be under-reported. I have got the fullness in the ear feeling. I'll read up on the ear popper, but I'll wait for a more definitive diagnosis.
