Wow, thanks CarrNan, thats exactly what happens to me, my symptoms aren't short, they'll last a day or 2, longest was bout a week, feel light headed from over thinking about my blood pressure, even bought a home device and when it gives me a proper reading, I don't believe it and will check it multiple times until I work myself up and then when I get a higher reading then I believe the machine is working properly, along with dizziness, my heart is pounding, I feel weak and fatigued,
