Hello there, my name is barney and im 17 years old I have a healthy weight and diet , when I was 14 I got some pains in my heart, I went to my GP she said it were only growing pains. When I was 16 im pretty sure I had a ischemic attack but dissmissed it not knowing what it was at the time. Now for the past few months I've been getting tingles in my hands, arms and my middle left side of my back. I have also been getting headaches lately. and a bit of nausea with slight sweats very unusual for me, with this I get a sudden flush of heat throughout my body apart from my hand. I'm wondering what all this could be. Any help would be gladly appreciated, thank you.
