R52: Pain, not elsewhere classified

R52.1: Chronic intractable pain

Chronic intractable pain is the term used to describe pain that persists despite numerous attempts at treatments and remedies. It often arises from conditions such as cancer, severe arthritis, and nervous system disorders, but sometimes the cause may be unknown. This type of pain lasts for more than three months and is constant, meaning it's present almost all the time, making normal daily activities difficult. The pain can be experienced in any part of the body and may vary in intensity from mild to severe. It remains even after the healing process of an injury or disease should be complete, due to the body's pain signals remaining active. It's significant to note that everyday stressors, lack of sleep, and other psychological factors can influence how someone perceives their pain, potentially exacerbating it.
