Trigger finger happens when the tendon that bends the finger becomes irritated and inflamed, causing catching, stiffness, or pain when moving. A steroid injection delivers anti-inflammatory medication directly to the tendon sheath, reducing swelling and allowing the tendon to glide freely. This simple, in-office procedure often brings fast relief and restores motion. For some patients, it can also help avoid surgery when combined with rest, splinting, or therapy exercises. #triggerfinger #painma
