Hi! I'm new to this site and wondering if it's POTS that I have.I'll try to keep this short. I have been to every doctor I can think of Family- vasovagel(sp) reaction to almost passing out in Winn-Dixie Rhumotologists(sp) ton of blood work (nothing) cardiologist -rapid heartbeat -echo-normal blood work-normal tilt table-normal hemotologist -ton of blood work-normal vein specialist-no varicose veins -calf pump works fine-ultrasound show no blood clots. Probably saw another doctor I can't think of right now! Any way, I'ts not that I passout often, Just get dizzy sometimes. Scares me when this happens in a store and I have my kids with me than have to drive home. My biggest concern is everytime I stand my legs and arms if hanging down turn all purple and spotted. I'm usually cold (OH) just remembered endo docter for hypothyroid because so my symptoms but blood tests were normal.Fatigue,cold,dry skin, sounds like hypothyroid doesn't it, maybe i'ts pots . I don't think they know much about it here in Louisiana. If anyone has this and knows what helps, please let me know. I am to ashamed to wear shorts anymore. Even in 100 degree heat out here I lood like I'm nearly frozen. e-mail tannagilbert@cox.net
