question: I just finished a run (3mi with my wife, slow) and never had to breathe hard. within 3 min of finishing I have left upper chest pain, periscapular pains, and in the proximal 1/3 of left arm. My heart rate was down to 60BPM and a little tightness in the chest. Back at home I have a little light headedness and a BP of 122/82. Im only 31 and pretty fit. Not sure if we should be concerned or not.
