Welcome to the forum, Don! My symptoms are very similar to yours, but I have a progressive neuropathy from hereditary nerve-muscle deterioration, which is untreatable.
You have been through an awful lot, that is a lot of spinal cord trauma, but it sounds like you are recovering. Most of us here do not have neuropathy due to sudden injury, but I hope someone who does will help you out. Also some of our regulars have experience with all types over the years and may remember a case like yours.
I hope that you continue to improve. Nerves are notoriously slow and arbitrary in their regeneration, so it may take patience, but good luck!
