WebMD lists upper left arm pain as one of the seven pains women should not ignore. In women, the symptoms of heart attack are often more subtle than in men. In individuals at high risk for heart attack, subtle discomfort radiating to the upper left arm is reason for concern.

Mayo Clinic recommends seeking emergency help if other signs of a heart attack accompany the upper arm pain or it includes a protruding bone or deformity. Pain sufferers should see a doctor immediately if there was a cracking or popping noise before the pain or there is any swelling of the arm.
