hi a few days ago i had food poising and was in so much pain i had to call 911 for a ambulance. wile i was in there my heart rate was 100 steady they gave me morphine right after he gave it to me my heart jumped to 155 plus and i felt like i was passing out and my arms went numb. it lasted around 50 sec or so to a few min i do not really remember just remember it being short! its been a few days since then and i went for a walk and now my ears started to ring on the walk and i mean ring bad for a sec and i lost hearing in my left ear and its still a little numb i feel a little anxiety on top of that now and heavy breathing .
