Infusion Set Changes

Hi everyone! I hope you are all having a great December thus far. I can’t believe how fast it’s all going! Anyway, this afternoon I did a new infusion site at 4pm and immediately started climbing. I did a total of 10 units to correct the high and am still at 330 4 hours later. Has anyone experienced this before? I am always insulin resistant when I do a new site but I found today to be especially bad. It is really frustrating when I’ve stayed on top of it and kept giving more and more insulin, but I still somehow manage to get above 300. If anyone has any tips for how to manage blood sugars after site changes I would greatly appreciate it!
