🌿 Overview
Trigger finger happens when the tendon that bends a finger becomes swollen or its sheath narrows, so the finger catches, clicks, or locks in a bent position and then snaps straight. It's often worse in the morning and usually responds to rest, splinting, and gentle treatment.
The tendons that bend the fingers glide through snug tunnels (sheaths). If a tendon thickens or the tunnel narrows, the tendon catches as it passes, causing the telltale clicking, catching, or locking. It's linked to repetitive gripping and to conditions like diabetes.
Many cases ease with rest from gripping, a night splint to keep the finger straight, gentle stretches, and time. A doctor can offer a steroid injection or, for stubborn cases, a small release procedure. A finger truly stuck bent, or one that's hot, red, and swollen, should be seen promptly.
Common signs
- Clicking, catching, or popping as the finger bends or straightens
- A finger that locks in a bent position, then suddenly snaps straight
- Stiffness and a tender lump at the base of the finger (in the palm)
