Hi I'm new to all of this and haven't even had a TTT yet. What is the criteria for hyperadrenergenic POTS? How is it diagnosed? I've had a rash around the back of my neck for years and since my fatigue symptoms started I get adrenaline rushes when I'm just about to fall asleep and even wake up in the middle of the night from adrenaline rushes? Does that mean I have hyper POTS? I hope not
