It is pretty normal - anything between 4ish and 7ish, is. Doing firgerprick blood tests for BG is a routine thing they do for all patients no matter how old or young, or what happens to be wrong with them, in our local hospitals - same as doing your BP and temperature - and in my view that is correct procedure for everyone.
5 months isn't long to expect nerves to heal when they've been ill and dying for yonks already. Nerve damage is either sudden and traumatic - I did this to my left big toe when I dropped something heavy on the nail bed, and didn't regain the feeling in exactly half of it, was really weird, full feeling everywhere except half that one toe. Literally in recent weeks, it doesn't seem quite as 'numb' as it was. Or very slow indeed like when people have high blood glucose for years either without knowing it or because they don't treat it seriously and obtain the proper treatment, or when they do obtain it - don't follow the regime.
But - when did I drop the heavy enamel grill pan on it? August 2011 !!
To do a proper fasting BG test, that means while you are still in bed, just after you wake up, before you put a foot on the floor. Were you?
