In the past week or so, I've noticed the area around my heart has been tight and uneasy. I feel my heart and notice it going faster then usual and it only makes sense with all the stress I've had lately. My left arm and back are also hurting. I don't have a primary care doctor and I'm starting to feel like it's a bigger issue because my sleeping habits are being affected as well. I could just go to the ER but I'm not sure really what to do.
