What should you know about heart muscle strain?

A strain usually refers to an injury of skeletal muscle, such as the chest wall, back, neck, or thigh muscles. The heart is a different type of muscle and chest symptoms can also arise from the heart, lungs, digestive system, or nerves. Pain that changes with pressing or movement may fit a chest-wall problem, but that feature alone cannot safely rule out a heart-related cause.

Stop exertion and note when the symptom began, what it feels like, and whether movement or breathing changes it. Do not self-treat presumed muscle strain if the symptom is new, unexplained, or recurring with effort. A clinician may need to examine you and arrange tests before recommending rest, treatment for muscle strain, or rehabilitation.

Call emergency services for chest pressure or pain with breathlessness, sweating, faintness, nausea, unusual weakness, or pain spreading to the arm, jaw, back, or shoulder. Seek urgent help for severe or persistent chest pain, a racing or irregular heartbeat with dizziness, or symptoms that begin during exertion. Do not drive yourself if you feel seriously unwell.

Ask what causes have been considered, which tests are needed, whether activity is safe, and which symptoms should trigger emergency help. Mention any recent exercise, injury, infection, or medical condition.
