Hi Sam H, ((( Smiles )))

So you were useing a nasal spray that contained mercury..
Thats terrible that they put that in there.
So you got really sick but you said you had some improvements...
So you had/have auditory problems from it.
You said it was painful to listen to music/watch t.v.
You mean it literally hurt's your ears???
literal pain, like a toothache or a sharp stabbing pain or dull aching pain ect??
If thats what your describing I know how that feel's as I had ear pain like that for along time though I had hyperacusis disorder.
Do you get any other symptoms in your ears??
Do sounds sound louder to you is that why it hurts..
Have your auditory problems got better??
so you may have seen some slight improvement already with some of your symptoms..
Sound therapy TRT & Pink Noise can help restore normal sensitivity to sound..
Sound therapy is used in some cases of autism as well.
And I do believe autism can be caused by mercury exposure too.

Here's a thread of people that are sound sensitive and have problems with hearing certain sounds was this your problem too??

Lots of people with ear pain over there too.
I hope thats better for you..
Ear pain, sounds sounding too loud, middle ear spasms, distortion ect....
Lot's of that there too..
And sometimes it makes me wonder..
What can cause the vunerabilty to theses condition.
I hope your feeling better.

Take Care
