@56pan Maybe the PET scan will reveal something positive? We can still hold on to some hope can't we? I am positive that the neuropathy can be crippling. I have it in my hands and legs below my knees. I live with compression gloves and knee high socks. I also go through tubes of arnicare gel. They seem to help. At least that is what I tell myself. I have been in wheelchairs, so I understand. Waddling is sometimes the only way to get around. I actually can talk like donald duck, so I have tried to have some fun with it in the past. Wow on the vision. I can only imagine the frustration. I agree on having to play the hand that you are dealt. I wish that I could get some new cards and start the hand all over again. I have too many deuces and not enough aces. Keeping plugging away and hope for the best. That is all we can do sometimes. Good luck to you sir. Let us know how things go ok?
