I don't have the numbness. Tho since I was a kid my feet would get hot on the soles like I was standing on a hot plate. And some of my toes would go numb. I've done that since I can remember. I go barefoot alot so I don't have the problem as often I also wear only leather shoes and that helps.
I had a small tumor taken off of the base of one middle finger on my left hand a few years ago. I was so worried I would lose the use of that hand. I have lipomas which are fatty benign tumors. I had a large one taken off at the same time as the finger. I had been told there was a 50/50 chance I could lose the use of that hand. I didnt lose it but the finger the little tumor was in he must have gotten too close to a nerve because it is slightly numb all the time. But it works fine and I don't even notice the numbness very often.
I've had the stabbing pains for several years but only got diagnosed with diabetes about 4 yrs ago.
I do deal with leg cramps and they make my feet pulsate when the nerves get going in the bottom of my feet. They ripple and it is the funniest frustrating hurting feeling!
As long as I eat bananas at least every other day I don't have the leg cramps so much. But bananas are hard to keep and I end up going without them for too long. I wanted to take pills but the dr and the pharmacist thought that was a bad idea. They didn't really say why.
