I agree with some of the others. Oral taper never did anything for me following IVSM, in fact the few times I did do the oral pred, it only made me sick.
Call the doc that rx'd the oral pred and let him/her know what is going on with you ASAP. They need feedback if they are to know how to treat you.
Good luck with the college orientation...stay plenty hydrated. Sounds like you're going to need it.
Keep us all posted, we care.
