Glucose Level of diabetics?

I saw a neurologist for the tingling in my left foot and she confirmed that my toe has no feeling and nothing can be done. I exercise my feet anyway because I suspect the problem is a result of my back surgery which was really serious surgery. I wear socks in the evening and in bed until 2:00 a.m. and then take them off because I am too warm. Also my left knee has pain since the back surgery and I had no problem with the knee replacement before the surgery. The other knee replacement is fine. I don't think the diabetes is causing the tingling so long as I exercise some and wear socks for the cold feet. I am not likely to become an athlete at my age, because I never was that interested or capable. I did march in high school band, and that was it. I could sweat playing Rachmaninoff on the piano, however.
But that's about it from now on. So I refuse to have both shoulders replaced because I don't want the risk or more nerve damage.
I manage the pain most days pretty well with Icey Hot. I haven't started anything rash like Brandy or more pain pills. I don't take any over the counter pain meds at all. The best course for everything is exercise, so long as I don't fall. Then I can't get up. I call 911. It is embarrassing when I slip off a chair in my nightgown. At least my mind is staying steady. I can work two Sudocku puzzles a day. Dorisena
