Dave, glad you are doing better....Dang nasty bug <_< That is scary....I had those real high fevers a couple of months ago, they said it was from my sinus infection, like 102.7. Temps like that happen in kids, but, in adults it can be dangerous. You did the right thing going to the doc...15/Ryan is great place, it's been our drs. for years. Your elevated heart rate was probably from the high fever.
Get lots of rest and we'll talk when you are better,
Lisa
