Sugar water shots ease shoulder pain in new study
NCT ID NCT04805242
First seen Jun 27, 2026 · Last updated Jul 02, 2026 · Updated 1 time
Summary
This study tested whether injecting a sugar-water solution (dextrose prolotherapy) into the shoulder can reduce pain and improve function in people with chronic rotator cuff disease. Sixty adults aged 30 to 65 with shoulder pain lasting more than three months took part. The treatment aims to stimulate healing and provide symptom relief without surgery.
