I think you are experiencing something very common when you've done your bolus maths and sorted out a basal dose that seems right for you then a seemingly random spike happens. It is very frustrating when you are not in control of your own body seemingly.After about a week of feeling really good about my blood sugar levels -- 90+% time in range, no huge spikes -- suddenly yesterday I kept spiking up to 16/17 and got down to 46% time in range. Measured on Libre 2 but also confirmed via blood pricks.
I haven't seen numbers that high in months but haven't changed anything. I do a fair amount of regular exercise and haven't changed insulin or ratios for a few months.
Twice these spikes were well after meals, and as I shouldn't have had any insulin on board I took some correction insulin. The first time I also went for a walk and had a mild hypo, then a more severe one later.
With BG of 14 before bed (and I thought no insulin on board) I took two units. I was told that my correction factor is one unit for 2.8 so this should have lowered me to a safe level, which has happened before. But 1.5 hours later I was at 3mmol!
I'm just so confused because every time I feel like I have a good week something like this happens and feels so frustrating. I don't think it's anything I've done wrong or differently, but I'm open to hear anyone's suggestions or ideas because otherwise I really don't know what to do in these situations.
Thank you!

That eliminates a few possibilities. So you mentioned you were active once you caught the spike, what were activity levels like prior to that?nope, nothing has changed at all aside from a new insulin cartridge this week, so I’m really hoping that’s the culprit
Unused (unopened) insulin left at room temperature can be returned to refrigeration but must be used within designated days of initially being stored at room temperature. It shouldn't have ruined it as long as you use it within the time frame of it being left out at room temperature.Thank you all for suggestions and advice! I switched my Humalog and turns out that was indeed the culprit; I opened a new cartridge on Thursday and then immediately the spikes returned to normal levels and I'm back at 85-90% TIR.
What I was confused about (and why I didn't immediately recognise this) is that I was having these crazy hypos - going from 16 down to 4 in a couple of hours.
Additionally I have no idea what caused the insulin to go 'off'. I flew to the UK last week, taking the cartridge as a spare, and forgot to put it in the fridge once I arrived. So it was out of the fridge for ~4 days, then I returned home and put it back in the fridge when I got back. Then opened it two days after that. Could that temperature fluctuation have ruined it? I'm just surprised as I know it can survive out of the fridge for a month, so assumed that would be fine!
