I am a 19 year old male, for the past 1-2 months I've been experiencing a variety of symptoms. These symptoms include: heartaches, chest discomfort, and recently I've been noticing aches in my arms and legs. I went to the ER about a month ago. My EKG, blood work, and chest x-ray were all normal. Are the symptoms I'm feeling relating to my heart? Or are these conditions symptoms of anxiety?
