hey, i have been randomly getting mild chest pains on the left hand side of my chest, my heart will sometimes start beating faster lasting from a few seconds to a few minutes, this will happen a few times a day, ranging from not less than 5 and up to 20(maybe even more i loose count). also have mild pain in the left side of my jaw. I have been to the hospital and got my heart scanned by EKG (i think its called) and have had Xray's, and blood tests, the doctors told me that my heart is fine, however i beg to differ, I use to drink ALOT of energy drinks ranging from 1 to 3 litres daily, also use to be a heavy smoker but have recently given up and use to eat very fatty unhealthy foods such as macdonalds pizzas and deepfried foods on a daily basis, i weigh only 62 kgs and i am only 21 years of age 175cm tall and not keen to die yet... also have been getting heart palpitations after smoking hence why i have recently quit smoking
