The last 3 weeks I have had my blood pressure go from my average of 110-1200ver 60 something to 135 to168 over 60+70+80+, at the same time I get really hot and sweat a lot, get headaches and have trouble swallowing. This is only when I an sitting ,resting, not when I am standing, walking or working. I am just turned 65, had thyroid cancer in 86, so no thyroid, had a hysterecomy 20 yrs ago, so what is goin on.
