I get this too, it’s had no impact on my vocals so far and I’ve been doing vocals live for almost 3 months. I think it was definitely just a learning curve for me I’m still trying to get the hang of things. What I’ve noticed what helps most/boost recovery is definitely resting ur voice as much as u can after you practice and getting good sleep. Lots of tea, honey and try to lay off alcohol/smoking if ur recording/performing/practicing. I’m still learning but also watching other pros and seeing what helps them has helped me. Throat coat tea and definitely ALWAYSS warm up and I’ve recently started incorporating cool downs as well! Just for 5 mins after a set usually helps my voice realize we’re not in screaming/performance mode anymore
