So I have a number of medical issues including chronic pain all over my body, so typically I'm not immediately worried by severe pain. Recently I started a new job, long hours on my feet. Ten hour days. About half way through my shift last night I started having fairly severe pain, around my sternum. It started out as more of a severe ache, but near the end of my shift it changed and began to feel more like muscle spasms. I have a relatively high pain threshold, but by the end of my shift it was all I could do just to manage the pain and still move. Pressure on the area, just a couple fingers pressing into my sternum, seemed to alleviate most of the pain. Today the pain in my sternum is gone, but I have a dull ache in the upper right side of my chest around the breast/pec area. Some preliminary googling suggests possible coronary artery spasms, which can be a precursor to a heart attack, particularly if they last for a long time. Sounds like most coronary spasms last for up to 30 minutes, but this was for hours. I don't have medical right now, and I'm not really sure what to do. I could go to an urgent care, but from my experience in the past they are for colds and minor injuries and aren't equipped to deal with anything serious. Getting medical will take weeks to a month, whether I go through the state or wait for my jobs medical to kick in. As I said I'm used to having a lot of issues and just toughing it out, but it seems like I could possibly die if I do that here. Should I go to an ER? Would they be equipped to run the right tests and give me heart medication like nitroglycerin for the time being? I'm really not sure what to do here. I need money but I'm worried if I keep going back to work I could have a heart attack.
