Oh my goodness! That kind of dizziness is - indeed - frightening. You are wise & prudent to monitor your your blood pressure! My husband experienced a similar predicament a few years ago. He had a circumstance with fluid deep down inside his inner ear canals that caused the dizziness. The doctors explained that only solution was to lie flat on his back in bed until the fluid worked its way through, up, or out. He had thought his "back was out of whack." One doctor wanted to do surgery -- all because he was wet behind the ears! Take care Dear! You are one of our favorite buddies & we want you back on those (toning) ropes soon!
