started with heaviness and pain in chest and throat with rapid heart rate. had ekg some blood work and chest x ray all normal. now having feeling of burning in chest throat and stomache. waiting on upper GI reports to come back. when i first all these problems i was doing alot of screaming and under alot of stress. could the rapid heart rate be because of stress and could the chest,stomache,and throat been from the screaming? i've had this problem now for six weeks. i need to have a little relief from worrying about it.
