I’ve had several plastic cannula bits which are supposed to be inside of me but aren’t when I take the needle. They are bent at 45 deg? How it managed that I don’t know. Wet patches yes but as my intake general is only 3-4 units it doesn’t emerge on my clothes until I have the raging thirst and need of the loo at 25mmol. Oh the joys of not having a functioning pancreas.
