I was diagnosed a few years ago with acid reflux. I also have anxiety on top of it. I take meds for both. Lately I have been having chest pains, pain in my left arm, the center of my back, and headaches daily. I'm 28 years old, but not very active. Are these pains anxiety or heart related? I'm terrified it is my heart. And that's all I can focus on which only makes the pains worse. Please help! I am afraid to eat anything that I would enjoy fearing that it will damage my heart. I am afraid to exercise. I am so out of shape and tired of worrying!
