Duffy has sarcoidosis, a disorder that causes the growth of inflammatory cells on different organs of the body. In her case, her sarcoidosis is located in her brain, causing her unimaginable pain. In this powerful, inspirational, funny, and important manual for surviving pain, Duffy draws on her experience as a patient advocate, certified recreational therapist, and hospital chaplain to illuminate gratifying methods people can use to cope with chronic pain and reinforces the sentiment that "circumstances determine our lives, but we shape our lives by what we make of circumstances" (Sir John Wheeler Bennet). More than one-third of the US population--nearly 113 million Americans--is currently living with chronic pain, while another 133 million Americans live with some form of chronic illness. Half of the US population lives with the challenges of these invisible illnesses where their symptoms are not always obvious to the casual observer. Addressing a country ravaged by both chronic pain and opioid addiction, Backbone offers a salve of self-sufficiency, spunk, and perseverance.
