Hi my name is salvador I get sharp chest pains 1-2 times a week. i workout 6 times a day I do take preworkout evryday of those days that I workout. I usually do 8-12 reps on all of my compound movements and excercises. im 20 years old I weigh 185 and im 5 6. I feel like a sharp pain on the inside of my chest. And i eat about 4,000 calories a day to gain muscle mass. i go no.2 about 3-4 times a day so its not like my food is plugged up. i drink a gallon of water a day. I eat 5 meals a day. Alot of oatmeal 4 potatoes a day and 20 oz of chicken breast a day everyday. Thankyou.
