If things sound louder, then you probably have some loudness hyperacusis as well. I remember my turning signals sounded uncomfortably loud, but now they don't.
The sound distortion could be some dysacusis, which I haven't had, so not familiar with.
You do need to be patient with all of this. It can take a long time to see any improvements for any of these issues.
You could always go and see an audiologist, but just be careful to avoid louder hearing tests. Tell them you think that in addition to tinnitus that you have TTTS, loudness hyperacusis and maybe dysacusis.
Not sure what you are talking about. TTTS isn't painful. Hyperacusis can be painful even if it is the loudness type - that is what is pure hell. I know all about being in meetings and on conference calls, cringing in pain, backing away as much as possible, leaving the room on fake toilet breaks. People sneezing or coughing was horrible too, sounding too loud, painful and causing me ear fullness and cramping of middle ear muscles. The worst.
