From a western clinical standpoint, gout is a prototypical crystal‑induced arthritis. Sustained hyperuricemia allows monosodium urate crystals to form and deposit in joints and periarticular tissues. When phagocytosed by resident macrophages and neutrophils, these crystals trigger NLRP3 inflammasome activation and robust interleukin‑1β release, leading to the explosive synovitis characteristic of flares. Standard of care aims to rapidly suppress this inflammation (NSAIDs, colchicine, corticosteroids, or IL‑1 inhibitors in select cases) and to prevent recurrence by maintaining serum urate below the saturation threshold using urate‑lowering therapy (e.g., allopurinol, febuxostat) with a treat‑to‑target approach. Acupuncture is considered a nonpharmacologic adjunct that may modulate pain and inflammation through neurobiological mechanisms. Experimental work shows needling can activate endogenous opioids and adenosine A1 receptor signaling locally, dampening nociception. Electroacupuncture has been shown to interface with autonomic reflexes, including vagal–adrenal anti‑inflammatory pathways, which could theoretically attenuate the cytokine cascade during flares. Improved microcirculation at and around joints may also contribute to symptom relief by facilitating edema clearance. Clinically, randomized trials—primarily small studies from China—suggest that adding manual or electroacupuncture to conventional therapy during acute flares can reduce pain intensity and joint swelling and may shorten the time to meaningful relief compared with usual care alone. Effects on functional recovery are variably reported, and sustained changes in serum urate are inconsistent. For chronic management, preliminary data indicate possible reductions in flare frequency and improved joint function, but heterogeneity in acupuncture protocols, brief follow‑up, and risk of bias limit firm conclusions. Notably, major western guidelines do not currently include acupuncture in gout management algorithms due to these evidence gaps. In practice, acupuncture can be integrated as supportive care—especially when pharmacologic options are limited by comorbidities or adverse effects—provided it does not delay initiation of evidence‑based anti‑inflammatory therapy during acute attacks and does not replace long‑term urate control. Safety is generally favorable with trained practitioners, though caution is warranted in anticoagulated patients, in the presence of suspected joint infection, or with implanted cardiac devices when considering electroacupuncture.
