I think the flushing is from the pvc, and I believe they can be cause from hbp. My son ended in the hospital 3 different times, pvc symptoms then all goes away. Heart dr found nothing when testing, except right when he is having the flushing, hbp, and pvc. Then they say anxiety meds.-- well the anxiety comes from the feelings of thumping, missed beats and heart going too fast then suddenly going slow again, the flushing feelings etc, etc....
He had to quit smoking pot, it was raising his bp too much and causing these, no caffeine, no diet pills, no speed of any kind. Now, completely normal. His bp has been high since 16 years old, but they never gave him meds for it. He is now 20.
Now the headaches--i had migraines for 8 years, every week or 2, for 8 years. Usually last 3 days in a row.(no lights, no sound, laying in bed) they finally gave me a migraine med that was a miracle drug and they would stop the migraine before it would start--you know when the spots come before your eyes--take meds and no migraine. But for years I knew it was my bp. I would sweat like a boy, but they never found high bp when I would go to the Dr. 140/95 or so. But when they finally diagnosed hbp it was 168/105. And then they put me on meds, have not had a migraine since then. Come to find out I am one of those pple who started out with low bp--105/65--even as low as 95/60. So when I was 140/95 I was already high for me. And extremely high.
Then finally had a heart attack that made me be on 2 different bp pills and low and behold my bp returned to normal 105/65.
But another strange thing--when my spinal cord was damaged from my spinal condition my blood pressure returned to very low, do not sweat anylonger, and I have trouble keeping my body temperature up. My pressure was 90/45 freaked me out--but many of the old symptoms went away--even when they find my pressures high now. No sweating, ever, no headaches, ever, cant keep myself warm. I was so accustomed to the sweating--now I feel cold without it. I am cold without it. Strange huh??
