I tested tonight and got 291 and an hour later I tested at 349! I've never tested that high. I not only didn't feel so good...understatement!...I didn't know what to do about it!?? Should I just sit around? go to ER? Thank goodness it's dropped to 170. Still not great but not so scary! Plus, and here's the really frustrating part of this disease, I don't know why it happened??? I didn't do anything that different. I'm pretty new at this and could REALLY USE SOME HELP!!!
