Did you know that when you use a heating pad to take care of a sore back you are making the problem worse?When you hurt your back,the muscles not only get tight but also get warm,and when you put more warmth on your back it will make those muscles tighter because you put more warmth on muscles that were already warm.The best way to take care of the problem is to put an ice pack on it,because it will relax your muscles and help them to unwind.
