I’ve been having horrible chest pain for almost 2 years. I also get really sharp and stabbing pains that are severe. I have had x rays, EKG, scope, and also echocardiogram. My chest is also swollen. Now I have been very tired and not sleeping at night. I am getting really bad headaches. I don’t want to do anything! Not even hang out with my friends. I’m 16 and just want my life back! Does anybody have any ideas or know what may be wrong??????? Please answer!!!!!!!!!!!!
