Endogenous Opioid Pain Control at the Site of Injury: Clinical Applications for Peripheral Analgesia

Immune cells at injury sites release opioid peptides that control pain locally through peripheral opioid receptors — a clinically exploitable mechanism for pain relief without central side effects like addiction and sedation.
