Like "usually when u get a steroid shot ur bg will always go up. its happend to me before and it usually stays up for a couple of days until it wears out. the first time i got a shot my bg went up in the 400s it scared me so i went back to the dr and told me it was normal cuz steroids to that to diabetics. that made me mad, he shouldve told me that before i stuck more insulin n me.
