Hi, I am a 17 year old male with acid reflux. Lately, i have been getting sudden sharp chest pain above my heart that will bring on a moment of nausea. Also, i get really random chills at unexpected times along with that sudden chest pain. At my physical, the doctor listened to my heartbeat, and said it was fine. I am extremely worried about this. Could it be acid reflux? Or anxiety or stress?? I weigh 230 pounds. I even get pins and needles in my left hand, and jaw and neck pain on the upper left side near my jaw. Maybe its all muscular?? It would be nice if this is not my heart, as i worry ALOT. Thank you
