Hugs from a fellow high blood pressure sufferer.

It could very well be that the chest pains you are experiencing are due to the high blood pressure.

Try to stay as relaxed as possible until the appointment - you don't want to push it any farther. And if the pains get bad, or you get a strange wooshing sound in your ears with your heartbeat, go to the ER because those are signs that your pressure is dangerously high. Also watch for headaches and beleive it or not, general crabbiness too. Did they give you a med to take?
