What is Trigger Finger?
Trigger Finger (also known as 'stenosing tenosynovitis') occurs when inflammation narrows the space within the sheath that surrounds the tendon in the affected finger.
The finger or thumb may become stuck in a bent position.
Your finger can bend or straighten with a snap, like a trigger being pulled and released, hence the name.
What are the symptoms?
Pain, stiffness, and a sensation of 'locking' or 'catching' when you bend and straighten your finger.
How is it treated?
Rest, splints and stretching exercises can all help with Trigger Finger.
Your doctor may also suggest a steroid injection, percutaneous release (where a needle is inserted into the tendon) or surgery.
