Hi all need some advice please I was diagnosed t 1 in November I started to get a hold of my sugars but since Thursday they have been very high up to 18s, I've read about a correction dose to bring them down how do u do that and also do u do inselin before food or after I've been doing it after could this be my problem, because I can't have sugars to high as my back is starting to hurt again it was pain in the back that took me to docs when they found my sugars were high thank you in advance.
