Hi hun, you have NO idea how it feels to finally learn someone else has this condition. I have been on so many ECG'S, x-rays etc and all comes back normal but I am CONVINCED this is heart related. I have a massive phobia of a heart attack and it is driving me insane. My doctor has told me its just anxiety but I don't believe him. I get pins and needles in my arm 24/7 and it hurts, I have fainted from the panic. I get this when I do not even have anxiety attacks when I get this and this is why I do not believe this is anxiety. Im only 21, slim and eat healthy with no family heart history problems so I can not understand why this is happening. I am always in a&e, doctors, walk-ins......and I get the same result all the time. My anxiety is that bad now I cannot leave my home. xxxxxxxxxxxxxxxxxxxxxx
