I agree...when my pain is uncontrollable my BP spikes and I know it right away. My GP has been very concerned about it and told me that if my BP goes up and down quickly due to pain, then I can have a stroke. I had to monitor my BP at home and call in my readings once a week. One day he called me back and put me on Topol because he was so afraid that I would have a stroke. It has worked out well and I have had VERY few days when it will spike high. I have also started using No Salt on my food and cooking, so that helps a lot.
