Julie, Its interesting to see on your signature that you are on antihistamines and singulair, im trying to work out how it all fits in but i have asthma, food allergies and allergic rhinitis and am wondering how much of an impact taking control of my allergies will have on my pots? Im so new to this and have got soo much to learn, i cant help but think this is a condition that you have to resrarch and act upon yourself as the health professionals seem to know so little about it, im seriously thinking of printing off the articles and sending them to my dr!
