I was diagnosed with pots a month ago when I went to the emergency room with chest pains and umbness on my left arm. After seeing about ten different doctors I was referred to a cardiologist who is currently treating me. I was always healthy, active and have no medical history. I did overwork myself and have been very stressed for the past year therefore I thought I had a nervous breakdown. I had no test done like stress test or tilt test but when I stand or sit my heartrate goes up..but it has happen while I sleep as well. This is scary for me as I have four kids to take care of and a full time job. I really hope they find a cure for this thing, I have asked for an MRI but was denied. currently taking salt tablets, drinking lots of water and gatorade..please give me some advise..I am going nuts!
