progress is going to have to start up again from a dead standstill but yeah i'm pretty sure you can start rehab again. the problem is going to be that your body healed over whatever was fucked with your hands - so in order to undo that you're going to have to break them down again
that means working them to their limit just like you work any other muscle out to break it down, so it grows stronger. you need to stretch your fingers, flex them, contract them, squeeze them together, spread them out, wiggle them, tap finger-to-thumb in increasingly quicker sequences of patterns, use increasingly harder grip-trainers, and again, SWIM. my pinky improved a lot when i started swimming semi-regularly, the resistance of water without the risk of overexertion really helps. if you can't swim, just filling up a bucket of water and doing hand-work inside of it could help too
but you also need to rest. it's not the work out that grows the muscle or mends the nerves and tendons, it's the hours and days AFTER. work hard, but don't push yourself so far beyond your limits so as to make it worse, and then rest. it could take a year, maybe two, but you'll definitely see improvement
and since you have a form of resistance in your music, also do that. working your hands by playing the instruments themselves will help regain coordination, dexterity, muscle memory, and will provide a micro-workout for the fingers and everything else.
there's lots of hand strengthening exercises too, from "bodyweight" stuff like hooking your fingers together and trying to pull one finger closed against the force of the other, to steepling your fingers together and pressing and curling them knuckle to knuckle, to small exercise bands, to even shit like filling a bucket with sand/rice (i recommend rice) and trying to squeeze the material as tight as you can
just NEVER. GIVE. UP. hand injuries are virtually impossible to fix surgically - you are on your own if you want your hands back
