So about a month and a half ago I broke my picking hand in 3 places and i'm trying to get back into it. Now that the cast is off and I can play without said cast scraping my strings annoyingly, I wanted to know if there are any techniques for strengthening my wrist and becoming more dexterous.
Ten years ago I smashed my fret hand. I had to wear a brace and had pins sticking out of my hand holding it together for months. I have some nerve damage, but over time it has gotten much better. What helped me get over it and get back to where I was on guitar was just to play. Don't overdo it, if the injury starts to hurt, then take a break. If a certain playing style or motion causes more pain, try something else. It'll come back with time.
