Applying heat to the muscle can also be beneficial. Moist heat, such as that from a warm bath or shower, is better than dry heat from a heating pad. A warm bath can soothe the area and reduce the pain. This is because the heat helps improve circulation, as well as your body’s metabolism. It also relaxes the muscle, which decreases muscle spasms and stiffness in the ligaments and tendons. Adding Epsom salts to the warm bath can also benefit a pulled muscle.
