Chronic pain

Chronic pain is pain that can happen for longer than 3 months. It is also known as gradual burning pain, electrical pain, throbbing pain, and nauseating pain. This type of pain is different to severe pain, which is pain similar with a cause that can be relieved by treating the cause. Chronic pain can last for years. Persistent pain often serves no apparent useful purpose.

The most common types of chronic pain are back pain, severe headache, migraine, and pain near the face.

Chronic pain can cause multiple psychological and physical effects that sometimes continue until the end of life. Analysis of part of the brain (damage to brain neurons) found that, insomnia and sleep deprivation, metabolic problems, chronic stress, obesity, and heart attack are examples of physical disorders; and depression, and neurocognitive disorders are examples of mental illness.
