I'm sorry to hear that. The main problem for me with the distortion is the stabbing pain that comes with it, everytime I hear anything above a certain loudness threshold, which isn't even that high. My own voice makes it react at just a moderate speaking level.Not so far, no...
Do you have/did you have this pain/hyperacusis? If so, did it improve in any way? I think I could habituate to the distortion/reactiveness itself, but the pain that comes with it is just unbearable.
