I’ve been suffering from bouts of high blood pressure spikes for years now and when I had insurance my doctor suspected it might have something to do with my kidneys, but then I lost my job and insurance so I never got to do all the tests he wanted me to. Now my blood pressure can go high up to 250/150 and then I need to get to the ER for a medication that brings it down to my normal 130/80. Other times it goes far too low, and at times I had blood pressure of 70/50. I know it’s only guessing without doing the tests and seeing a doctor, but does anybody have any idea what might be causing this?
