Manifestations of Chronic Pain

摘要

In 2006, according to the National Center for Health Statistics, 76.2 million Americans -one in every four-experienced pain that exceeded 24 hours, and millions more had acute pain. The CDC reported that, in 2016, 37.7% of adults never had pain, 42.8% had pain some days, 19.6% had pain most days or daily, and 50% to 75% of hospitalized patients in their last days of life died in moderate-to-severe pain. In a study, 20% of adults (42 million) reported that pain or physical discomfort disrupted their sleep at least a few nights per week, and 86% reported an inability to sleep well. Two-thirds of pain sufferers expected to live with some pain for the rest of their lives, whereas 30% expected to become pain-free from a cure or treatment.
