Upper-left arm, chest or neck pain can have various causes, ranging in severity from 'needs attention' to 'critical'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose upper-left arm, chest or neck pain, we could:
|Mitral Valve Prolapse||90%||Confirm|
|Heart Disease||2%||Ruled out|
Do you suffer from occasional and unusual pain that is in your chest, upper left arm, or left side of neck?
Possible responses:→ No / don't know
→ Occasionally / moderate
→ Often / severe
In cases of heart disease, pain will usually be felt in the left or middle of the chest, but it can also be felt in the inner sides of the left arm, neck, jaw, or between the shoulder blades.
