I have pain in my right shoulder and neck, is this sign of heart attack?

Possible: If pain in neck and shoulder comes with movement of neck or shoulder and is reproducible then not heart related most likely.

neck pain: At age 33 shoulder and neck pain is usually of musculoskeletal origin though in some patients it can be caused by cardiac ischemia. Your dr. Can generally tell easily if neck/shoulder pain is musculoskeletal in origin.

Unlikely: At your age, risks are always the key. The right sided pain in heart attacks are less common. If there are no risk factors, like hypertension, dm, high cholesterol, smoking and family history and drugs, the incidence becomes even less likely. If you can reproduce the pain like with moving the neck with stiffness and palpable tenderness present, mi would be a rare diagnosis with that presentation.
