Inflammation Both Worsens AND Relieves Neuropathic Pain: Dual Opioid-Mediated Effects

evidence
The takeaway

Inflammation conferred dual effects on chronic neuropathic pain: initially worsening via neuroinflammation but also providing opioid-mediated relief through immune cell opioid peptide release — a paradoxical anti-/pronociceptive balance.
