My name is Mina. I m 24 yrs old and I weight 111lbs. I went into the vitamin shop yesterday to find products to help burn fat and built. I specifically told the sale rep that I did not want anything that made me feel cracked out or gives shakes and hitters and he handed me OxyElite. I took one pill as directed and within an hour my heart pounding out of my chest for almost 6 hours straight. I developed a sharp pain on my left side of my chest right about my breast and today it feels like my upper chest area is so sore. I would like to know what caused my entire pectoral muscle to be so sore now? And what can I do to relieve or heal the soreness? And should I have seemed medical attention due to what I was felt for the duration of time? Should I still seek medical attention today?
