Symptoms & Signs. Pain in the arm can result from a number of factors. Abnormalities or injury of the skin, nerves, bones, joints, blood vessels, and soft tissues of the arm can all result in pain. Arm pain, depending on the location and cause, may be accompanied by numbness, redness, swelling, tenderness, or stiffness of the joints.
Pain in the arm can also be a sign of decreased blood flow to the heart (angina pectoris) or heart attack (myocardial infarction). The sudden onset of weakness or numbness in the arm, especially if it is occurs on only one side of the body, can be a sign of stroke. Seek immediate medical care (call 911) if you have upper arm pain, believe you may be having a heart attack, or experience sudden weakness or numbness in one arm.
