Kentishman,
This is a question that keeps coming up from time to time. It would seem from previous postings that there is a correlation between feeling cold and diabetes, I know this winter I have felt it more than ever. Accepted its been a cold winter this year, but even indoors I feel it more than in previous years.
As for a sign of low blood sugar, it would be wise to test to confirm or rule out, hypo syptoms do present some strange signs in different people, so always best to test for peace of mind.
I know this may seem strange, but since tightening my diabetes control I feel that I am more sensitive to both cold and heat, can't for one moment think why, but I am! :?
