thank you so much for your help.
the reason she has to change the length of the needle is that it is possible that 4mm no longer goes deep enough to get to her blood supply, so she doesn't get her full dose.
she refuses to be injected directly into her stomach, so we inject into her arms and legs (thighs).
it was interesting to find out to know that even adults are using the 4mm size with out any issues. maybe its due to the differences when you inject into your stomach and when you inject into your limbs?
thanks a lot for your help. her father has told me he has ordered 5mm 32G through a pharmacy, although he does not know the brand yet. I am a bit skeptical, as i have researched this thoroughly and have not found this size.
as "everydayupsanddowns" mentioned, only Novatwist has that size, and it only works with their pen, as it is a twist and click needle (something new).
well anyway, lets see what progress we make, i hope her dad gets the size she needs.
your help has been much appreciated, really it has.
if there as any more advice you have for us, or think we are making the wrong decisions, please feel free to advise us. i look forward to it.
