Littlelola, I have had a tilt table test before... The test last only until you pass out, I ended up taking up almost the full half hour. 29 mins into it I passed out. It's a very boring test and I felt funny having all these doctor's and nurses in the room basically staring at you for however long it takes you to pass out. They watch your heart rate and blood pressure. Not scary just boring.
No, my legs didn't hurt, but of course I was 12 year's younger then lol. During the test they will spray nitroglycerin under your toung to help speed the process along they do it 10 min's in and they do it for 3 time's 10 min's apart from each other.
