Question: A 55-year-old man with a history of chronic back pain decided to wean himself off of long-standing high-dose opiates. As he self-titrated down his opiate dose, he developed increasingly severe abdominal pain. To alleviate this pain, he applied a heating pad to his abdomen on a daily basis, a practice that he continued for a 6-month period. He presented to our clinic for evaluation of his abdominal pain and reported that the heating pad helped to ease his pain, but that he had progressively developed a rash over his abdomen.
