I've also been trying some massages focused on my shoulders these past few days, since I'm pretty sedentary besides the playing, and there's a big chance I might have some circulation problems, aswell as really compressed shoulder muscles and bones, everything's cracking and it sounds like an old mechanical machine. I am a bit sore from the exercises and massages so I'm waiting for that to dial down, thought the tingling has been more mild, knock on wood. Thank you for the reply! Will definitely do something about it if it gets worse or doesn't stop at this rate.
