High BP?

Since I've been so stressed out and in alot of pain, something weird has been happening.  My face turns bright red and gets hot, and my heart feels like it's racing...and now I'm nauseous alot.  The past couple times I've been to the doctor my blood pressure has been a little high, even though when I'm there I'm not usually having these symptoms.  My blood pressure used to be low from what I remember.  Are these things a sign of high bp?  How do I lower it?  I'm sure they don't like to perform surgery on people who have that...

:-(  I just got home from St. Pete where Chris will be till thursdayish for a DUI symposium.  Just me and the Charli.  :-(
