Fibromyalgia is the most common centralized pain disorder, affecting up to 3% of the population. Current treatments are incompletely effective, often poorly tolerated, and costly: there remains an urgent need for novel, effective, and well-tolerated therapy. Preliminary data suggests that vestibulocortical stimulation (VCS), or irrigating the external ear canal with temperate water, could rapidly improve pain and quality of life in this cohort. The VIPR trial will assess the efficacy of a single session of VCS - a safe & cost-effective bedside technique using a plastic syringe and temperate water - relative to sham in treating pain & improving quality of life using validated patient-reported outcomes.

Inclusion Criteria:

• Provision of signed and dated informed consent form

Deidentified individual participant data will not be made available because participants did not provide consent for data sharing beyond the scope of the present study. Aggregate data supporting the findings are included in the article.

A blind-to-hypothesis approach will be used. Investigators and participants will not be blinded to temperature of water as the procedure itself does not lend to it.
