There are a few answers to that question. If you are concerned about your blood pressure immediately because something doesn't feel right, you should seek immediate medical attention. Go to the medical clinic if it is open, ask them to help. Go to the Emergency department if it is open and ask them for help. If neither are open, find someone to drive you to the nearest doctor or urgent care clinic. Not an option? Call 911.
