Most chest pain isn’t a sign of anything serious and often isn’t caused by a heart problem. Nevertheless, it’s important to get it checked out. Heartburn, chest infections, muscle strain, and anxiety can all cause chest pain. Some of these can be alleviated with chiropractic care. More serious causes of chest pain include angina, pericarditis, and a heart attack. If you experience sudden chest pain that spreads to your arms, back, neck or jaw, causes you to feel short of breath, sweat, or feel/be sick, and lasts more than 15 minutes, it’s essential that you call 911 immediately as you could be having a heart attack.
