Arizona, I would definitely ask his dr. about the procedure. As U know, my husband is type 2 diabetic, and his circulation is horrid, that is why he is on so many meds., plus like your dad, he has that nueropathy. For the last year it is now going into his hands, and although I think he takes it well, I know there are days he gets very frustrated. At times I see hubby getting a lil depressed also, as like U said, when they have been so active all their lives, this is a horrid setback.
Hubby, and all my family have been into ham radio for over 30 yrs., and he loved to work on those radios, but now he has a very hard time, as he can't feel those parts that need to go into them for repairs. Many times I have to be extremely careful asking him to do many things, as he is losing so much feeling in his hands now. I'm sure this aggravates him, but I just try to do things and tell him I just felt like doing them as to not hurt his feelings. I doubt he will have that procedure for his neuropathy, as when he is checked, his circulation is good, the pain and numbness is what is being treated now.
When his heart arteries were clogged, his cardio man decided to do this roto rooter thing. He explained it was a new thing, but thought it would be best and would make for a faster recovery. Naturally they had an OR ready just in case they had to do angioplasty or anything unforeseeable, but luckily it all went fine. He went in on a monday morning and was released wed. morning. We expected him out tuesday, but dr. wanted one more day to make doubly sure all tests came back fine. He walked out of that hospital fit as a fiddle, in fact we actually visited with friends before coming home, as they took me to the hospital to pick him up, so he decided to stop for coffee.
Don't know if U go with your dad to his dr. visits, but maybe U could and have a good heart to heart talk with him. I feel for you, as I have been thru it and it is very hard to see someone U love be sick, and even harder to see them depressed. Think it over and possibly talk with your dad and see if he just might want both of U to speak with the dr. I truly wish U and your dad the best, it isn't easy to not know what to do next.
Best wishes, and a BIG prayer for your dad....
