Tinnitus That Goes Away with Valsalva or by Plugging Ear and Pulling Slightly?

Hi everyone,

I always thought my tinnitus was stress-related or due to earwax, which I recently had professionally cleaned out. But recently it's come back while I've not been stressed and my ears were completely fine.

It's a high-pitched tone in my right ear and and I've noticed I can make it stop completely by:

1. Holding my nose and blowing (Valsalva manouever). It's gone until I swallow and the tinnitus comes back along with my normal hearing.
2. Plugging my ear with my finger and ever so slightly pulling/applying outwards pressure.
3. Yawning (it comes back when I've finished yawning).

There's a distinct point with 1 and 2 where it stops, to the point I can turn it off and on if I slightly adjust my finger back and forth; It seems very physical. I don't have any of the other symptoms of Eustachian tube dysfunction, besides when I do the Valsalva, my ears seem to block/pressurize at different speeds.

I haven't seen an ENT yet but I'm trying to arm myself with as much knowledge as possible first.

Does anyone know what this could be?

Any insight would be greatly appreciated!
