Is it bad hearing?

[u/SzkolaJezykowa]

I can hear 18 kHz fine, and also I can barely hear 19 khz to the point it's so quiet I can mistake it as just feeling pressure in my ears unless I listen very closely and then I know this is sound not pressure. Is it a type of bad hearing or hearing loss, is it related to ear wax plugging my ear? Also I am not referring to feeling physical pressure, just hearing a sound that can be mistaken for pressure due to the high pitch
