Well I have some amazing news... I saw the nurse on Friday as planned. She couldn't have been nicer, more jovial or welcoming. She was delighted with my record-keeping and absolutely astounded I keep my blood glucose levels so tightly controlled.She also noticed I had a couple of instances of lipohypertrophy which 3 doctors had failed to diagnose (these have only recently appeared and only seem to be connected with the large amount of insulatard I have been using but I had seen the doctors about them because of how sore the area was).
Without even having to ask (and with no bullying about my weight!), she's put me on a double-concentrated insulin for both basal and bolus. The disappointing news is these aren't available in the glass cartridges to use in my nice metal Novo Nordisk pens - they're only in disposable plastic pens.
I haven't picked them up yet but have enough of the old insulin to tie me over a couple of weeks. So it seems I did a lot of fretting and worrying for nothing...!
