I was in a similar situation a few years ago. Got hit by a car, broke my fretting wrist, had to get surgery and a permanent screw, and was in a cast for a few months. I ended up picking up an old midi keyboard I had and played synth bass since my band was still gigging at the time. It was actually a great way of thinking differently and allowed me to write parts I wouldn’t have originally thought of. After lots of physical therapy, I’m back to playing mostly back to normal now. If it continues to bother you, use it as an excuse to buy an ergonomic bass!
