i have pulsatile tinnitus in one ear and a "normal" tinnitus in the other since early childhood or birth, and the whoosing/pulsatile tinnitus was a bit worse when i had covid because what causes the pulsatile tinnitus to begin with is a narrow ear canal which gets worse with swelling when you're congested. i also didn't know i had it because it was so normal to me until i read stuff about it because of covid. i felt like it took some extra days for that specifically to go away, but as a whole tinnitus is very subjective, when you start actively paying attention to it you'll always hear something. but both my standard tinnituses are back to normal which means i don't hear them unless i concentrate really hard, feel better soon and see a doctor if you're dealing with any kind of hearing loss!
