I’ve had angiograms that showed no blockage. EKG’s clean. But i do have high blood pressure. I sometimes get heavy pressure in my chest. I will chew 2 aspirins and the pain will soon ease up, but then I am incredibly thirsty. I can drink glass after glass of water, or any cold drink and still am thirsy. Anyone with medical background have any idea about these symptoms. No medical facility can seem to diagnose anything but High BP
