After many years of saying to different Drs that I know their is something wrong with me.....I was finally diagnosed with POTS Syndrome. Long story short, I had a allergic reaction to Benedryl and ended up in the ER. I ended up staying 2 days in the hospital because my HR was so high. After many tests and DRs visits POTS was brought up. I looked it up online and just kept crossing up symptons and causes while I read. Anyone else out there with POTS that can help me to understand it better. I am currently on a BetaBlocker, Effoxor and lots of vitamins (BComplex/multi/Vitamin C/Pottasium). Anything that my Dr is missing (tests/drugs/advice)? Just any information that can help me out. Thanks!
