Actually, given that you had already confirmed medically that you have experienced a slight elevation in your blood pressure, the question you should be asking is if the elevated blood pressure might be a symptom of something else. Since the elevated blood pressure is already confirmed a little less than a year ago, now we need to add increased sweating and facial flushing. And of course, the nausea experienced after mild exercise. First off...whatever else you glean from answers in this forum, you need to consult with your physician. Individually, these symptoms may not be such a big deal, but most definitely the collective of two or more is certainly pointing to a problem. When two or more symptoms combine to induce a negative outcome, chances are you are experiencing a significant and adverse health event. In your case, you should be concerned about possible cardio or vascular disease. The good news is that if these symptoms are relatively new, you might be looking at the onset of a disease process and consulting your doctor right away could forestall a more dire outcome.
