When acute pain lasts for weeks into months then it is called chronic pain, and the body begins to behave differently. Chronic pain prevents sleep and often results in daytime fatigue, poor concentration, irritability, and difficulty dealing with others, including family members, friends, and co-workers. For those who juggle caregiving with careers, chronic pain can make life seem overwhelming with feelings of anxiety, anger, depression, hopelessness, and even suicide.
Chronic pain is relentless—and expensive, with social costs in disability and lost productivity estimated at more than $100 billion annually. Chronic pain causes nearly 40 million visits to doctors and other health-care providers and can extend hospital stays, hinder recovery, and intensely change your quality of life.
