I am a young 13y old girl and I lately started having really bad heart problems. I would move and suddlenly I would blackout and feel extremely dizzy when I walk I nearly collapse and My vision goes all black then my heart starts beating so hard, fast and irregular and it hurts alot and then my head starts to hurt really bad I start to feel like I'm getting hot then my ears feel like they will burst while my limbs just don't really function and they get really sore I have to lie down or I will faint. The attacks keep getting worse lasting a few minutes I feel sleepy and exhausted after it with my heart still irregular and everything else still hurting alot they only started last year but sometimes in my everyday life my heart justs start beating randomly.
