Reading another forum of adult type 1...it was so dismaying to read what years of pricking fingers have done to them. We seem to use the same 3 fingers on each hand. Very rarely I use pinky unless at night and I'm having trouble with the others.. I started using thumb(it seems to bleed the best), but think its a little painful...Are you using creams..anything to prevent long term callouses? Or does it just come with the D territory over time?
