This trial is testing two types of injections, ketorolac and triamcinolone, to help patients with painful conditions in their shoulder, elbow, wrist, and hand. These injections aim to reduce inflammation and pain, improving movement and function. Ketorolac is a non-steroidal anti-inflammatory drug (NSAID) known for its potent nonopioid pain-relieving activity, effective in treating moderate to severe pain, especially after surgery.
