I seem to have a similar issue although mine's not as high as yours and it's only when I go to the doc so I'm lying the blame there. My norm is about 97 to 98 and my normal BP is around 120/60 (I know cause I got a home BP tester thingie). When I see the docs, my temp is in the high 98 to low 99 range and my BP is around 140/80ish. It's probably just nerves Grey. I wouldn't worry about it, especially since you've had all those tests done.
