I’m over my cold now (yay), but i’m still having trouble with my sugar… my basal rate day round has climbed by .2Units per hour, and my BG is still hovering up to 190, before and after eating. Bolus, wait and hour, 190. Bolus again, wait another hour, 190, ect ect. Bolus, eat, two hours later… 190.
I had a day like this today too.
I set my basal to 120% percent now and will check for lows in the coming hour. Try slightly increasing your basal (by 5-10%) and see if it helps.
You may need new basal rates!
While you claim to be over your cold, sometimes it can take quite a while for your body to “heal.” Your body is still dealing with all the inflammation. Remember, your bodies response to a cold or flu is a huge immune response. It could take days or in some cases perhaps weeks to fully get back to normal. I had the flu last year and had elevated blood sugars for a month while I recovered. You are young, I doubt it will take a month, but it may linger a few days past the point where huge green glops of goo drop frrom your nose.
If you change pods, but you may want to change the bottle of insulin you are using to a fresh new bottle too just in case it’s the insulin.
That’s been happening to me a lot lately due to allergies, I have a CGM and can see my stubborn BG’s in real time (causing me to stress out even more). Hands down, the one thing that helps kick start a drop is cardio exercise, go for a run, bike whatever. Much better than stacking your insulin.
What everyone else has said - and just to add that I usually need more insulin the day after I think a cold is over than I do during the cold. This doesn’t happen with flu-like illnesses, just colds for me. Good luck, hope you are doing better tomorrow (and don’t go hypo!).
I would temp basal also, starting at 50 percent increase (since you are already getting 2 units an hour), then increasing to 75 or even 100 percent if you see no movement downwards. At some point, your high cycle will break.
Okay, got it down. It took a nice bike ride, and then +50% basal for the rest of that day. Woke up the next day at 65, and was really glad to see it down. Ran kinda low that day, and now i’m back to normal (80-140) 
I was getting 1.8 during my peak then. That was .2 units over normal for me… still have that there, so i guess my basal rate just went up a bit. Oh well, got it under control now
Happy things are back to normal!
