Hi Tinkerersdaughter
Welcome to NwuroTalk

.
I am sorry to read about all of your problems.
Two forums that it would be worth checking out are peripheral neuropathy (
https://www.neurotalk.org/forum20/) and RSD/CRPS (
https://www.neurotalk.org/forum21/).
If you describe your experiences in them I am sure that you will get support and helpful suggestions from other members.
All the best.
