I may have asked before but I'm gonna ask again...in the morning I have to have an angiogram and maybe have a stent put in my right leg. I'm violently allergic to the dye, so I've got to have IV steroid prior and then by mouth for a few days to prevent angio-edema. I know already from a prior experience that my BG will sky rocket and I'm prepared for that to happen because I just have to have it and pray it works, but is there any wisdom out there? I think I'll be able to take what comes, but have any of you had something similar and can advise? I know if it gets too high I can ask for short term insulin treatment, but how high is too high???????
