Pain is an unpleasant sensation coupled with individualized unpleasant emotions. It is easier to treat acute pain than chronic pain because chronic pain can lead to maladaptive behaviour. Chronic pain is best controlled with multidisciplinary pain management.

Keywords: acute pain; chronic pain; pain pathways; nociceptors; neurotransmitters; neuropathic pain; pain management; analgesic agents
