Hi Michelle
I'm sorry you're feeling so crummy. I find with the 'roids, I'm extremely warm/hot and I'm usually a freeze baby. Maybe a cool shower would help.
As to your blood sugar, I ask my Dad who has diabetes. He says you're doing the right thing, keep a close eye on it and to call your doctor. If it gets up to the 500 range then it's getting to serious territory.
I'm not sure I was much help, but just want you to know you are not alone.
