I can relate to the poster here. My anxiety for most of the time was heart related. Worried that something was wrong with mine because my anxiety always seemed to stem from feeling uncomfortable in the chest area and arms. I've had so many ekg's done over the years, chest x rays, blood work and everythings came back fine. I started taking Zoloft and felt like I was getting ahold of my life. But I keep having the anxiousness and it's not all day it's at periods of the day. For instance today, I felt ok most the day. But i'm at the store and my left arm feels uncomfortable(one of my typical anxiety symptoms) and then I start worrying and work myself up into anxiousness. So now i'm home, took a anti anxiety med, and just laying here thinking what the hell, why do I have to have some type of anxiety episode during the day.
