Prehypertension. fatigue. dizzyness. **PLEASE help*?

The symptoms you describe are more consistant with low blood pressure not high blood pressure, more specifically orthostatic hypotension. I would wait until you have insurance and then get a regular check up. Those machines are usually inaccurate and it`s best to have one done manually by a trained professional. It`s good that you are concerned, high blood pressures over a long period of time can really cause a lot of cardiovascular problems. It sounds like you are doing a great job taking care of yourself, keep up the good work! :)
