Hi Jo
I agree with you on this! I never had any problems with 'mix yourself' needles but I find the 'pre-mix' needles are invariably blunt. Occasionally I get a batch that aren't too bad but it doesn't happen often.
When I mentioned it to Healthcare at Home they said I should try injecting into a different place, the skin in the area I use has become tough and thickened!! But having injected in the same way for four years without any problems it seems more likely to be the needles rather than my skin

I don't inject the same spot each time just the area (left side of stomach is less painful for some reason!) but quite often end up with a bruise these days.
Thought it was just me getting soft!
