I’ve been working on a house with no heat for the past few months. Today after lunch a few of my fingertips started to get numb, which seemed a little odd to me. The cold type of numbness, similar to being outdoors in freezing weather without good gloves. The temperature inside was probably 45 degrees or so, maybe 40. But I’ve been working in temperatures colder than today on many other occasions recently including all morning. The only difference about today was my BG was elevated when it happened, about 170. ( I screwed up my lunch bolus.) My BG when I am working is usually pretty flat or dropping.
Does a temporary spike of BG contribute to numb fingers in cold weather?
