My husband is 57 & has type 2 diabetes (has had it for 25+years), hypertension, high cholesterol, obesity. Yesterday he seemed fine. Today he says he does not feel well, did not have an appetite although he did eat dinner, had chills and sore legs and a small headache. He is sleeping a lot. He is on an insulin pump and other meds. what could be the problem? He last tested his blood sugar around ten am PST and it was around 120.
