I have had CFS for many years and was doing well enough. In sept I became severely ill with POTS. Heart races upon standing, severe headaches and nausea plus worsening fatigue and weakness. How did any of you treat or did you overcome any of the Oi/POTS? I don't have low blood pressure so florinef or licorice not options. Does Cheney or Myhill or Sinatra protocol help? Does it get better or does it just stay this bad? I have increased salt and fluids. Not much change. Any help or suggestions? Homebound now from this and can't get to specialist? Supplements or meds? Were any of you able to start walking and standing longer after a period of time?
