hello, about a week ago i consumed 1.75 16 oz. monster energy drinks, and an 8 oz. red bull. I am 151 lbs, and I had 350 mg. of caffeine in under 3 hrs. Ever since that day, while doing excersize, and during several strenous and violent sports, I've experienced a small chest pain where my heart is, it does not bother me enough that I have asked to go to a doctor. I have a normal heat beat, as far as blood pressure i am not sure, but I am worried it could be some kind of damage to my heart from the 120 beats a min. I was experiencing from the caffeine that I consumed. Could you tell me why I might be experiencing this kind of pain so I can consult a physician about a check-up or not?
