Use Heat
Before starting any physical activity, heating your injured muscle could be helpful in loosening the tissues. You can do this simply by placing a heat pack on the pulled hamstring. Let it sit around 5 minutes and then replace it with an ice pack in around 3 minutes. In general, heat can increase blood flow to speed up healing, while cold can reduce blood flow to alleviate the swelling. Avoid heat therapy when your injury is still swollen and painful. [5]
