Heat
Another simple home remedy for arm pain is to apply heat. You can find hot packs, tubs, or showers and apply them directly to the affected areas. Heat can help blood vessels open up, thus allowing more blood to reach the sore muscles. This will help them recover quicker and speed up your healing process. Avoid this option if your arm is still swollen. It is better to alternate between cold and heat therapy to have a better feeling. Be careful with the temperature to avoid a burn hazard. [8]
