I don't hear nonexistent music, but I used to constantly smell odors that didn't exist. It's been exactly 8 months since my injury, but I still sometimes smell odors that nobody else can smell.

What sucks is that the imaginary odors are incredibly repulsive. I smell things like feces, rotten food, etc. It drives me insane.

The good thing is that there are days when my house is super clean because I scrub it like crazy to get rid of the nasty smells that don't even exist lol.
