Yesterday, my glucose shot up again after the decadron infusion, aka prednisone, to over 600. It was so high it only registered Hi on my two glucose monitors, meaning it's over 600, and doesn't read anymore. I had to inject myself with short and long term insulin all day, night, and It's down to 422 now, still high. I'll see what my radiation center says, and didn't want to miss a day to go to the ER, but have the weekend off in a few hours to decide.
