What is Arm Pain?
By Brian Joseph MillerMedically Reviewed by Sanjai Sinha, MD
Arm pain, usually on the left side, accompanied by a tightening of the chest, nausea, and difficulty breathing can be a symptom of coronary artery disease or even a heart attack.
Arm pain can be caused by a wide variety of problems, ranging from joint inflammation and injuries to compressed nerves and trauma. A person with arm pain experiences soreness, itching, numbness, or discomfort in the structures of the arm.
Arm pain is usually caused by an injury, irritation, or inflammation of the skin, muscles, bones, or joints in the arm, although everyday activities, including typing, writing, working with tools, playing sports, lifting heavy objects, or exercising can cause arm pain.
