Hi good folks hope you are all keeping safe and well I use a Medtronic 640 pump and have noticed that for the past 4/5 changes I have made to infusion set, my BG's shoot way up before finally settling down after about 8 hours. Today I went from BG of 6.7 around 11.30 to over 14 after set change and lunch. Chucked in temp basal for 2 hours at 150% and took an extra 10 units of Bolus. Its finally starting to come down, now at 7.3. Anyone else experience a similar issue ?
