Presuming yr bofyweight hasn't increased and the pods and pda are ok, its possible that you need to increase your basal rates to deal with the high bg. Even though you did a TBR of +20%, it wasn't enough as you still needed to do corrections.
Out of panic, you used some Tresiba but that wont work straight away so will probably tickle yr bg levels later today so you will need to eithrr wait for Tresiba to vanish, or do a much higher tbr on the pump, or do some basal rate testing and adjusting.
its possible that you might be starting to come down with a bug and some slugs as high bg can often preceed any feelings of being unwell.
Hope you get on top of things again
