I am a 25 year old male. About 7 months ago I started having panic attacks. When I went to the doctor I thought I was having a heart attack, but they did an EKG, chest x-ray, blood work, and a thyroid test. Everything came back normal. They put me on Effexor XR and xanax for the panic attacks. Still, my chest continued to hurt on the left side, in my left arm, and my back on my shoulder blade. So I went back to the doctor and they did another EKG and all was normal again. This pain seemed to go away for about a month, but now its back and I cant get it off of my mind. I dont know if it is heart related or if its my anxiety. Is an EKG and the other tests sufficient enough or should I go to a specialist. Does anyone have some advice i am desperate. Thanks so much
