Hi im not sure whether i have diabetes or not atm iv had some contrasting readings but was just looking rfor some advise, iv had this ulnar nerve contrapment for months now and was just wondering if diabetes can effect your nerves straight away or if it tends to happen when youve had it a while. Its just iv been to my doctor and iv told him iv had reading of like 8mmol and a few others after eating but because iv had a fasting reading of 5 and 5.1 for the 3 month reading he says its doesnt matter what the random and readings after meals are. Iv read that this is not true. Im having othe symptoms like the hunger and urinating more. Also just having tingling in my arms and in my foot was just wondering if it was common for this sort of thing to come on quickly? Would appreciate any advice im really struggling with it, thanks.
