I have concerns about looking for a diagnosis of possible syncope? I am 32, 5 5 , 110 lbs. I have faintness, dizziness, tingling in face & pain in my legs. Problem seems to be worse in heat, during stress, usually do not actually pass out, but come very close to it often. Seems to be better if I drink ALOT of water & take ALOT of salt. Sometimes gets worse if I lay down, exercise also makes it worse. I urinate frequently, even when I am not trying to take excessive amounts of liquid to deal w/ issue. My blood pressure is normally very low, but I can feel it drop more during these episodes, others around me can even witness my face go white. Sometimes my vision becomes blurred during these experiences. It is also worse when I fly.
