My pain classification and how to use pain medicine

Abstract

Pain is classified into four types: inflammatory pain, neuropathic pain, psychogenic pain, and unexplained pain.

Medicines used to treat pain can be classified into non-steroidal anti-inflammatory drugs (NSAIDs), acetaminophen, extract from inflamed cutaneous tissue of rabbits inoculated with vaccinia virus, opioids, neuropathic pain medicines, and antidepressants such as duloxetine.

It is important to use different pain medicines according to whether they are effective against acute, chronic, or neuropathic pain.
