Opioid-induced hyperalgesia

From MEpedia, a crowd-sourced encyclopedia of ME and CFS science and history

Opioid-Induced Hyperalgesia or OIH is defined as "is a state of enhanced pain sensitization in patients who are on chronic opioid therapy".[1]

Opioid-induced hyperalgesia causes a much lower pain threshold, which means that pain is greater when opiods are taken compared to when they are not used - which is the opposite of a normal response.
