I was on Benicar for the past 5 years after my twins were born and that was for the cardiomyopathy. My cardiologist thought that taking me off that would make my tachy issues better- guess not. When I say "only POTS DX" I meant no other dx. like whatever the other dx. are that people have listed at the bottom of their posts.(Isn't that bad that i just read those things and can't remember what any of them are?) For the past year I've had they tachy stuff with the low bp but now I've been having the '"brain fog", more chest pain/ pressure, my legs ache when I sit even if they aren't crossed, seem to get off bal. more and dizzy more but not to the point of falling or passing out and my stomach seems just more upset lately. Oh yeah, and tired. I was so embarassed tonight. I was helping to collect money at this jewelry training I was at and for some reason a lady gave me $25 for the $10 she owed and I could not for the life of me figure how much change I owed her! It makes me mad! I know I'm not stupid but that's how I feel lately. Then I go back to thinking, this is all in my head and I'm just being a baby which also seems to be a difficult emotion to figure out. Thanks for listening and for everyone's input.
