Immediate Action for Tinnitus Onset?

Is there a thread that lists the time sensitive, immediate, and possibly helpful treatments/actions upon tinnitus onset?

I am aware of
- Prednisone
- HBOT (Hyperbaric Oxygen Therapy)

 

Depends on what is the cause of T

These 2 are for noise trauma and sudden HL not specifically T

 

That's all I am aware of. You can try taking NAC.

Try to protect your ears from moderate noises like that of a vacuum cleaner.

 

How much NAC?
Is there a specific thread concerning HBOT?
Thank you!
