I’m just wondering what I should do… I’ve randomly tested while shopping at the mall with a friend and was at 498, a crazy high as I’ve been doing good with my diet and all. I double checked to make sure before I corrected the high and had the same result. I then corrected with 15 units, I have a 1:20 correction factor. I tested an hour later and was 370. Thinking that it would get better I waited and tested at the 1 1/2 hour mark and was 350 then at the 2 hour mark I was back to 400. I’m not feeling sick or anything but it’s been four hours and I’m still in the 400’s. I put in a call to my endo and am waiting but I know he’s going to tell me to go to the emergency room. I thought that maybe it’s bad/ out of date insulin but I opened this vial a week ago and it’s crystal clear. Before lunch my sugar was 152 and then I had 78 grams of carbs for lunch and took 5 units fast acting. I’m not sure if it was walking around shopping that raised me that high, but it’s the only thing that I’ve done “out of the ordinary”. Any suggestions? I’m just not sure what to do!
