Does your finger suddenly catch, click, or lock when you bend it—and then straighten with a painful snap? You might assume it is a minor joint problem, but these symptoms can be caused by trigger finger, a condition that affects the smooth movement of a finger tendon. Early assessment can help identify the cause and guide the right treatment before stiffness and difficulty with everyday tasks become more troublesome.
What Is Trigger Finger?
Trigger finger, also called stenosing tenosynovitis, occurs when a finger’s flexor tendon has difficulty gliding smoothly through its surrounding tunnel, known as the tendon sheath. The finger may click, catch, or become stuck in a bent position.
It commonly affects the thumb, ring finger, or middle finger. Symptoms may be more noticeable in the morning or after gripping objects.

What Are the Common Symptoms?
You may have trigger finger if you experience:
- Clicking or snapping when bending or straightening a finger.
- Pain or tenderness near the base of the affected finger or thumb.
- A finger that temporarily gets stuck in a bent position.
- Morning stiffness or difficulty opening your hand.
- A small tender lump near the base of the finger.
These symptoms can resemble other hand conditions, so an assessment is important rather than assuming every locked finger is trigger finger.
Why Does Trigger Finger Happen?
Trigger finger develops when tendon movement becomes restricted. Contributing factors may include repetitive gripping, diabetes, rheumatoid arthritis, and other health conditions. However, it can also occur without a clear cause.
Repetitive hand activity may aggravate symptoms, but it is not always the sole cause. Avoid blaming yourself or assuming that simply resting your hand will resolve the problem.
When Should You Seek Medical Help?
Arrange an assessment if clicking or locking persists, pain interferes with daily activities, symptoms are worsening, or you struggle to straighten your finger fully.
Seek urgent medical attention if your finger becomes suddenly stuck and cannot be straightened, especially after an injury, or if you develop severe pain, marked swelling, redness, warmth, fever, numbness, or a change in finger colour. These symptoms may indicate a problem other than routine trigger finger.
If your finger is currently locked and cannot be straightened, do not force it open.
Can Physiotherapy Help Trigger Finger?
Treatment depends on symptom severity, how long the problem has been present, and any underlying conditions. A physiotherapist can assess hand movement, pain, functional limitations, and activities that may aggravate symptoms.
Depending on your assessment, conservative management may include:
- Activity modification: Temporarily reducing forceful gripping or repetitive movements that provoke symptoms.
- Gentle movement: Using appropriate, pain-limited exercises when recommended.
- Splinting advice: A suitable splint may help some people, particularly when symptoms are worse overnight.
- Education: Learning how to manage everyday tasks without unnecessarily irritating the affected finger.
Avoid aggressive stretching, forceful massage, or repeatedly snapping the finger straight.
If symptoms persist, a doctor may recommend treatments such as a corticosteroid injection or, in selected cases, a minor surgical procedure. Physiotherapy can support appropriate rehabilitation, but it does not replace medical treatment when that is needed.

Frequently Asked Questions
1. Can trigger finger go away on its own?
Mild symptoms may improve with activity modification, but persistent or worsening locking deserves assessment. Improvement is not guaranteed without treatment.
2. Should I keep bending a finger that keeps locking?
Do not repeatedly force it through a painful click or snap. Use gentle, comfortable movement and seek advice if locking continues.
3. Is trigger finger caused by arthritis?
Not necessarily. Trigger finger involves restricted tendon gliding, while arthritis affects the joints. Both conditions can coexist, and other causes of finger pain or stiffness should be considered.
4. Does trigger finger always need surgery?
No. Treatment may include activity modification, splinting, or a medical injection. Surgery may be considered when symptoms persist or other treatments do not provide sufficient relief.
5. Can physiotherapy treat trigger finger?
Physiotherapy may help with symptom management, movement, activity modification, and rehabilitation in appropriate cases. Treatment should be tailored to the individual, and persistent locking may require medical intervention.
