Can Nasal Steroid Spray Cause Permanent Damage to Inner Ear?

[Rafaa]

So I've taken a nasal steroid spray and now have on and off tinnitus in my "good ear". This is how I discovered I have patulous (open) eustachian tubes so the steroid had easy passage to the inner ear.

While using it I could feel my ear drum feel wet and moving constantly with a weeoooo sound, like an ambulance.

Since then it has died down, with intermittent tinnitus. But I still feel some dull pain there from time to time, I read it can take months to dry out.

Just wondering if there's anything I can do to save myself from having permanent tinnitus there?

NAC, saunas, etc? Laser therapy?

Please help.
