First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested whether taking vitamin C before and after planned upper limb surgery could prevent complex regional pain syndrome (CRPS), a chronic pain condition. Nearly 1,000 adults participated, receiving either vitamin C or a placebo. The goal was to see if vitamin C reduces CRPS occurrence at 6 months after surgery.
