Guys, can someone advise me what I’m doing wrong. I have continuous troubles with infusion set almost every day. When my sugars go out of the control, I start to change the set and see the catheter is kinked or with air bubbles inside… I tried 9 mm in the buttock it works 1-2 days and I change set again. I also tried 6 mm in abdomen, and my sugar wasn’t under control. Could you please help me what to do, which site to apply the set I am thin and skinny, don’t have fat in my stomach.
