I notice he didn't respond at all on the diabetes front. knowing someone who has gone through all that to the bitter end is understandable justification for hoping it's something else, which Dal might be correct in figuring usually it is, and focusing on the nerves.

I have a brother with diabetes, my all-time best friend died from it after losing some pieces and his eyesight, I could list some others I know of.

For me, tingly fingers means maybe I need to change my immediate obsession and do something else because I'm sleeping the wrong way or something. Well, besides back pain, pinched nerves, MS, and clenching my fist too tight when knocking some sense into some hoodies. ha ha. like that ever happens.
