Thank you, The medication she takes is fludrocortisone, but I am not sure what dose, she is away in the city this week and will get to see the doctor again while she is there. She has had this condition since about Febuary last year and we spent many months going from test to test ruling out epilepsy and heart conditons etc, I am sure you would all be familar with this sort of stuff, getting sent from one specialist to another. Finally they gave her a tilt test, which I knew from what I had read was one of the few things that can diagnose stuff like this. So she was able to see a cardiologist in November I think that said she had "fainting" and put her on the medication. Her was actually really quite nice and went to extremes to try and settle us down and asure us it would be treatable and that there is nothing wrong with her head or her heart, but something wrong with the comunnication between. Her told her she had to stand up against a door every day for 15 minutes and start to exercise as much as possible, and then take it from there. I had made a mistake though of writing to him prior to the appointment stressing the need for him to take the time to read all the tests she had already had done and telling him that I thought from what I had read that she might have POTS. So I may have stepped on his toes a bit maybe, who knows. We live rural and in Australia so it is difficult to find doctors that might know more. Thanks for the reply's
