Agree that Loraine should be a good resource. What came to mind though is perhaps looking into alternate chords altogether. You can play beautiful sounding chords on just 3 strings, often only fretting a single note. I haven’t pursued this myself but I’ve seen videos come up on my feed and there are teachers out there who teach it.
If playing the traditional way doesn’t help you overcome your nerve damage, (it might since exercise ought to be a good thing, but I’m not sure) you might want to consider other approaches. Another would be alternate tunings. Joni Mitchell had polio when she was 9 and had very limited motion in her left hand. This lead to her experimenting with more than 50 alternate tunings (many that she invented herself).
