Trigger finger is a condition that affects one or more of the hand’s tendons, making it difficult to bend the affected finger or thumb.
If the tendon becomes swollen and inflamed it can ‘catch’ in the tunnel it runs through (the tendon sheath). This can make it difficult to move the affected finger or thumb and can result in a clicking sensation.
Trigger finger is also known as stenosing tenosynovitis or stenosing tenovaginosis. It usually affects the thumb, ring finger or little finger. One or more fingers can be affected, and the problem may develop in both hands. It’s more common in the right hand, which may be because most people are right-handed.
Symptoms of trigger finger can include pain at the base of the affected finger or thumb when you move it or press on it, and stiffness or clicking when you move the affected finger or thumb, particularly first thing in the morning.
