Hi... I cannot give you a cure/ answer... But my son suffered them to a severe degree. He was hospitalised 3 times because of them and put in the heart unit. His attacks happened because he was attacked by a gang of men and assaulted in a strange city he was visiting. He became somewhat of a recluse after that, never wanting to go out, which lasted about 2 years ... When he did venture out again, that's when the anxiety began. It was a horrible few years in all... But it DID eventually cease And now he's just as he always, happy and carefree... Wishing you all the best.
