Since your ECG, TMT, and echocardiography are normal, the likelihood of significant coronary artery disease is reassuring. Chest pain persisting intermittently for 10 years with normal cardiac evaluation is more suggestive of musculoskeletal pain (e.g., costochondritis or myofascial pain), gastroesophageal reflux/gas-related pain, or anxiety/stress-related symptoms, though a clinical examination is required to determine the exact cause.
Health Tips
Seek emergency medical care immediately if you develop severe or prolonged chest pain, pain radiating to the arm/jaw, associated sweating, breathlessness, fainting, or palpitations.
