Brad, sorry for your situation. Mine started quite a few years ago due to two back surgeries which resulted in nerve damage - same result. Loss of feeling in my feet led to a recurring sprained ankle leading to a reconstructive surgery which eventually resulted in an ankle fusion. A new hip thrown in the mix and I have a challenge staying upright in the river.
Two things keep me fishing still:
Wading staff and a pontoon boat - they work for me.
I hope things will work out for your best solution. Know that I truly feel your pain, or, in this case, lack of any feeling. It is frustrating, but I admire your will and tenacity. Keep the faith and enjoy the continued ride.
"There will be days when the fishing is better than one's most optimistic forecast, others when it is far worse. Either is a gain over just staying home."
