4. Massage
Pain in the left arm felt when exercising can often be due to overuse of the muscle: In this case, the healthiest option is to stop the exercise and wait for the muscle to rest – doing anything else will only put you at risk of further injury. This can also sometimes happen in cases where you weren’t exercising, but instead were picking up something heavy – anything too much for the muscles to handle at that point in time.
Massage can be one of the best ways to bring relief to tired and painful muscles, and if you are experiencing repeated pain in the arms due to strain or recent injury, massaging, applying heat and resting the affected limb are the best possible things that you can do under the circumstances.
In most cases, massage can be done at home, but this can be difficult to do alone. In this case, make an appointment with a sports massage therapist.
