tendonitis
"I am taking this medicine for Tendonitis from shoulder to wrist. Before Naproxen I had zero strength and very minimal movement. After a week on Naproxen (after 2 hours) I have most movement and strength.

Side effects are nausea but it is mild. Apparently, the anti-inflammatory properties are just as beneficial to healing, as is the pain relief (relaxation of tendons). "
