Well - my new sets arrived in the post today and my DSN has asked me to try inserting them whilst being guided by the booklet and/or the short video clip on-line. She should know me by now - I'm not the bravest of souls and they look quite complicated (probably like everything, just a matter of getting used to them what really puts me off is the length of needle and cannula - longer than the quick sets which didn't suit me unfortunately). My basic question is - does it real hurt to insert these?
