Hi Sean, ((( Smiles )))

Noise and medications, illness, toxins ect...
Even though noise being the main trigger for hyperacusis..
Lots of things can trigger it too..
Hyperacusis is a symptom of many things..
But you wrote you had OCD.
Thats interesting because on the other board I'm on.
They have been talking about OCD.
There is a thread 5 pages long called Eating Noises Do They Bother You??
With people posting about all kinds of sensitivity to sounds ect problems..
SSSS4/Misophonia/Hyperacusis/ also maybe OCD ect..
Some say they have been diagnoised with OCD..
It's neurological based some of theses problems I do believe..
But when things are heard and expirenced as being Too Loud.
It's usually hyperacusis and that condition can be expirenced in a mild form to severe..
And also people can change in catagories of H over time.
It's an interesting subject theses sound sensitivity disorders..
The known triggers and unknown ones too..
Some people believe they know what caused it for them..
And some people don't know how it happened to them.
Hyperacusis is a symptom of something that went wrong.
Can be an acoustic trauma or nerve injury.

Take Care
