I’ve had like basic hand splint type things for my hands. My hand and fingers get really bloody sore doing anything. Something simple like Holding a plate is really hard for me. So have a little look online and see if there is anything suitable for you as they can make a difference. X

For wrists, I like KT tape, you can pull and tighten it to your liking, while still maintaining flexibility that you don’t get with a lot of braces & splints. For fingers, look into swan rings.
