Give the sore muscles a break until they’re not really sore anymore, it will save you future joint pain. A specific amount of time isn’t what is best, it’s the amount of time it takes to recover, however long that takes.
Don’t push past form failure either, once you can’t do the movement properly its time to go down to smaller weight or move on.
Using any tool that vibrate much like a string trimmer will irritate where my spine is pinched and I’ll regret it for months. It makes me feel useless. Fusing 4 discs in my upper back or neck would almost guaranteed make me feel more useless.
I definitely can’t pretend I’m young anymore. It isn’t just pain, and when it is pain it’s not the worst pain. It makes me unable to feel my arm. I had to get an epidural of steroids to get the inflammation down to get feeling back, and I seem to be at least mildly allergic to that .
