Final answer:
The correct term for persistent pain that isn't a sign of tissue damage is 'chronic pain.' It can be associated with an immune response, contrasting with neuropathic pain coming from the nervous system.
Step-by-step explanation:
The term for continuous or intermittent pain that does not serve as a warning of tissue damage is chronic pain. Chronic pain can persist even after the tissue has healed, often involving an immune response with components such as macrophages releasing chemical messengers that contribute to the sensation of pain. Neuropathic pain, another type, arises from damage to the nervous system and involves exaggerated pain signals being sent to the brain. Treatments for pain relief can vary greatly and depend on many factors, including pain severity and concurrent conditions.
