Pain in the Left Arm After Exercise

Pain in your left arm during exercise may be due to local issues or problems that involve other areas of the body.This pain can range in severity from a minor inconvenience to a life-threatening condition.


Pain during an exercise in your left arm may be a sign of ligament damage in your wrist, elbow or shoulder. Stretching of a ligament will cause pain during movement and swelling may also be present. A physician will diagnose this problem with a physical examination, x-ray and MRI. The treatment for ligament damage is immobilization, surgery or a combination of both.


Damage to the muscle fibers may also be the cause of pain in your left arm during exercise. Muscle fiber damage ranges from strains to tears. The symptoms of a muscle injury are pain, swelling and the loss of mobility in the affected area. Muscle strains are diagnosed by using MRI, physical examination and computerized tomography. A muscle injury is treated using rest and surgery.


Pain in the left arm may be a result of a pinched nerve. This type of problem may manifest itself through pain in the area of the pinched nerve. The pain may also travel down the trajectory of the nerve. Muscle weakness and numbness may also occur as a result of a pinched nerve. MRI and electromyography are used to diagnose pinched nerves in your left arm. A pinched nerve is treated using corticosteroid injections, analgesics, physical therapy and if necessary, surgery.
