Upper Body Discomfort
In some cases, the pain caused by a heart attack might spread to other areas from the chest. This leads to possible discomfort around the upper body, especially the left arm, upper back, abdomen, jaw, teeth, throat, shoulder, and neck. It is mostly a dull ache that only lasts a few seconds to a few minutes. If you have not done any physical activities or worked out recently, then pain in the upper body might be a possible sign of a heart attack. Make sure to visit your doctor as soon as possible to get proper advice. [4]
