Mine is still (always) present.
Since childhood, but perfect hearing.
Hell if I know.
Don't worry, any conditioning was broken years ago. Motherfuckers.
But the intense spikes are not present for what it's worth. Just my usual 'sprinkling stardust' but I 'see' it too with 20/15 again, hell if I know. Nor doctors KEK.
Glad to hear a few are getting relief though.
