I have had weirs hard palpitations for the past ten plus years. I have went to see doctors and i get the same response everytime, im to young to experience such symptoms. I will get a pain in my chest, stabbing kind of pain. It comes out of no where, then it hurts for me to breathe in. My left hand ,arm, and side of my neck feel as though someone beat me. My skin in these areas hurts to even touch, or move it. I get extremely tired as though i have been drained of all energy. My other episodes i will feel sick or tired a few days and then it willl hit me. Ill feel as though someone sitting on my chest, and i am in quite a bit of pain. Most of the time if ita late at night im scared to even fall asleep. Each year i feel it get worse and worse but im to tired of getting told im making this up. I have had family and friends witness each episode and still no closer to finding out what is going on. Does anyone have any similar symptoms?
