Need help knowing what I did to hurt my throat doing vocals(strained, etc.?). I was doing high growls/shrieks/rasps for a little while the past 2 nights and I'd get minor sore throat pain after a few minutes of doing it but would just fight through it and still keep doing those high shriek notes(it's not a scream like say Varg Vikernes did, it's using the same technique as a death growl except youre going higher and not using the O, I guess my black metal vocals are kind of a cross between a rasp and a shriek),when I was finished my throat felt fine, but this morning when I woke up my throat had an awkward feeling and felt shredded except there was no pain. Everytime I take a deep breath I feel a minor pain in the depths(deep lower part) of my throat which is very unusual, it neevr does that, I don't think I blew my cords out as I can still rasp/growl(only did it 1 time to see if I could still do it) and am not trying those all out high note shrieks until my throat is healed up, I don't want to fuck anything up for sure, I'm about to record a black metal EP so I'm definitely resting my vocals for a while. So could this just be a strain or what?
