Hi Michelle,
Sorry you're having to go through this!

At first, I thought you wrote that your
blood pressure was over 300.

I was going to type all caps for you to call 9-1-1
immediately!
Anyway, when on steroids, my blood pressure
and my blood sugar go sky high. They had to give me insulin shots the last time while I was in the hospital for infusions, then my eyes were fuzzy for a few weeks following, I'm assuming from the blood sugar.
What I did was avoid all sugar and most starches. That controlled it pretty well during the prednisone taper. I really sympathize with you, I can't stand steroids.
As the others have said, call the doctor if you start feeling bad.
