Mainly, it can cause burns and slowly dissipate the effectiveness of it. Heat, as well as cold (which you might try heat, then cold) will both help. They should be alternated. I don't mean stop one and start the other. Use good judgment and give yourself time inbetween. Know it's a pain. But please, don't burn yourself, and even worse start a heating pad on fire
