I am 43, 230 lbs, 5 4 . I was just shocked about an hour ago. I have a heart condition (POTS) and the mild burn is just below my left breast. My bp is 122/100, hr 90. My left arm and hand are going numb. Due to the location of the shock burnbeing so close to my heart and because of my POTS, do I have to go to the er?
Hi, I would recommend going to the ER for a physical exam, a resting ECG and cardiac enzymes in order to exclude possible coronary artery disease.  POTS is not a life-threatening cardiac disease, but the chest pain could be related to coronary artery disease.  An exercise cardiac stress test may be necessary if this situation persists.  Hope I have answered your query. Let me know if I can assist you further.
