I m a 53 yr. old male 6 2 , 250 lb. realitivly good health, on Blood Pressure medication. Last full physical in Jan 2011, my BP was fine, cholosterol was fine, Dr did a routine EKG and it all checked out. I have been weight lifting for 30 years and still do lift relativly heavy 4 nights a week. Casual cigarette smoker, non drinker. On May 5 went out to dinner with a group and got sick that evening (vomiting & diareaha) ~ blamed it on bad Mexican food although no one else got ill. since then, everytime I cut he grass, after about 15 minuites, I get chest pain high up in my pectorials and my left fore arm. I stop for 5 minuites and it goes away & I m fine. The cycle repeats for the 3 times it takes me to cut the grass. I will go to the gym in the evening and work out hard for 1 hr.(Bench press 250, squat 325, etc) without any problem. I tried to reproduce this on the stationary bike by hard pedeling getting my heart rate above 100 for 1/2 hr. I have no problem, can t reproduce the chest pain. After cutting he grass yesterday (same routine as before with the pain) going the gym last evening for hour with no problem, I woke up this morning with diarea. I m thinking of calling my Dr and setting up a stress test? or do I have a virus? or have I developed alergies to grass polen? Any advice? Thanx
