I am 33yr old single mother of 3 beautiful children. I am a survivor of Acute Promyelocytic Leukemia; I've been in remission for 4.5yrs. I was recently diagnosed with Postural Orhtostatic Tachycardia and was given a program to follow that involves consuming 10,000mg of sodium and 3liters of water a day. This disorder has been affecting my life in a negative way. My youngest is 15 months and it is hard to play with him beacuse as soon I as start I get bad palpatations and shortness of breath, as well as tightness is my chest. I am now being followed by some good Doctors after being ignored and not properly treated by the one I was referred to. I have been dealing POTS for 5, almost 6 years and was told to lose weight and everything would be fine but how can you exercise when you can't catch your breath after 2 minutes of treadmill. I need HELP
