Trigger finger develops when the flexor tendon, which helps bend the finger, becomes irritated or swollen. This can make it difficult for the tendon to pass smoothly through the pulley system in the finger.
Initially, symptoms may be mild and intermittent, but without appropriate treatment they can become more frequent and eventually cause the finger to lock in a bent position.
Although any finger can be affected, trigger finger most commonly involves the thumb, ring finger or middle finger and may affect one or several fingers.
Symptoms usually develop gradually and may vary in severity. Common signs include:
As the condition progresses, symptoms may become more persistent and interfere with work, hobbies and daily tasks.
The exact cause is not always clear, but trigger finger develops when repeated irritation causes thickening or inflammation around the tendon and pulley.
Factors that may increase your risk include:
Women are affected more frequently than men, and people with diabetes may experience more severe symptoms or involvement of multiple fingers.
Trigger finger can usually be diagnosed during a specialist consultation.
Your consultant will discuss your symptoms, medical history and any activities that may be contributing to the problem. A thorough examination of your hand allows your specialist to assess movement, identify tenderness and determine whether the finger is catching or locking.
Imaging is not routinely required but may occasionally be recommended if another hand condition is suspected or to exclude alternative causes of your symptoms.
At Mayo Clinic Healthcare, diagnosis is supported by a multidisciplinary approach whenever appropriate, ensuring that any underlying conditions contributing to your symptoms are also identified and managed.
Many patients respond well to trigger finger treatment without surgery, particularly when treatment begins before permanent stiffness develops.
Your treatment plan will be tailored to your symptoms, lifestyle and overall health.
Activity Modification
Reducing activities that involve repetitive gripping or prolonged forceful hand movements may allow the inflamed tendon to recover. Your specialist will advise practical strategies to minimise strain while maintaining normal hand function wherever possible.
Splinting
A finger splint may be recommended to rest the affected tendon, particularly at night. Wearing a splint for several weeks can reduce irritation and improve movement in selected patients.
Anti-inflammatory Medication
Non-steroidal anti-inflammatory medicines (NSAIDs) may help relieve pain associated with trigger finger, although they do not address the underlying narrowing of the tendon sheath. Your consultant will advise whether these medications are suitable for you.
Hand Therapy
Specialist hand therapy may be recommended to improve flexibility, maintain range of movement and reduce stiffness. Gentle stretching exercises and education on activity modification can support recovery and help prevent symptoms from worsening.
Corticosteroid Injection
A corticosteroid injection into the tendon sheath is one of the most effective non-surgical treatments for trigger finger. The injection reduces inflammation around the tendon, allowing smoother movement and relieving pain.
Many patients experience significant improvement following a single injection, although some may require a second injection or eventually benefit from surgery if symptoms return or persist. Corticosteroid injections may be less effective in people with longstanding symptoms or diabetes.
Choosing the right specialist is an important part of achieving the best possible outcome.
