Chronic pain is defined by its length (more than six months) and its resistance to conventional therapies. Acute pain is defined as 30 days or less. If you have chronic pain, there is help. Chronic pain syndrome is not the same as acute pain or recurrent acute pain. Acute pain is due to actual or pending tissue damage. Its duration is short and its psychosocial consequences are minimal.
