I agree, certain pitches really bother me (more than regular sounds)...i don't know if you are more likely to spike due to the kind of pitch or not. Is yours reactive tinnitus?
Yeah is it is now all these problems started after I had an MRI in 2017 which definitely gave me a permanent tinnitus increase. I never had muffled hearing though or ear fullness or any other symptoms apart from tinnitus increase and my hearing clinically has remained the same since I got to tinnitus over 6 years ago but these are not very accurate.
So it seems the more you damage your hearing the more easily you'll get spikes in the future.
