This is a different age, but I think the same principle applies. When I was 20, I started getting issues from excessive keyboard usage. It stayed for 5 years even though I cut down substantially & tried massages. I ended up rock climbing and my issues went away with larger muscles. I’m in my 40s now and still use the same approach: where can I build muscle and make the pain subside. It doesn’t take much muscle, normally 3-6 months of practice @ 2x/week. The results normally stick pretty long, even when I back off the practice.
