Introduction
Trigger Finger, also known as stenosing tenosynovitis, is a painful hand disorder where a finger (or thumb) becomes stuck in a bent position and may suddenly snap straight — much like pulling and releasing a trigger.
This condition happens when the tendon sheath becomes inflamed or thickened, making it harder for the tendon to glide smoothly. The result is clicking, popping, or locking of the finger, often worse in the morning or after repetitive use.
Trigger Finger is common among people who perform repetitive gripping tasks such as gardeners, musicians, and office workers. It also has strong associations with diabetes and rheumatoid arthritis.
The good news? Many cases improve with splints, gentle stretching, and lifestyle changes — often avoiding surgery.
Key Symptoms of Trigger Finger
Typical signs of Trigger Finger include:
Finger stiffness, especially in the morning
A popping or clicking sensation when moving the finger
Pain or tenderness at the base of the finger or thumb
The finger getting “stuck” in a bent position, sometimes requiring the other hand to straighten it
In severe cases, the finger may lock permanently in a bent or straightened position
👉 Symptoms may affect one or multiple fingers, with the thumb, middle, and ring fingers most commonly involved.
Causes and Risk Factors
Trigger Finger is caused by inflammation of the tendon sheath (the protective covering around finger tendons). This restricts smooth tendon movement.
Common risk factors include:
Repetitive gripping (tools, musical instruments, sports)
Diabetes – higher risk due to tendon thickening
Rheumatoid arthritis & gout – increase inflammation in hand joints
Age – more common in adults over 40
Gender – women are affected more often than men
Non-Surgical Treatments for Trigger Finger
1. Finger Splints
Wearing a splint keeps the finger straight, giving tendons time to rest and heal. Splints are usually worn at night or during activities that aggravate symptoms.

2. Stretching & Strengthening Exercises
Finger extensions – open hand fully, stretch fingers apart
Tendon gliding – bend and straighten fingers through full motion
Therapy putty exercises – strengthen tendons gently once inflammation subsides
3. NSAIDs & Topical Treatments
Over-the-counter anti-inflammatories (ibuprofen, naproxen) and topical gels (diclofenac) can ease swelling and pain.
4. Corticosteroid Injections
In moderate to severe cases, injections into the tendon sheath can reduce inflammation and restore movement.
Surgical Options
If non-surgical methods fail, doctors may recommend:
Percutaneous release – a needle is used to break up the tightened sheath
Open surgical release – small incision to release the tendon sheath
Both procedures are usually outpatient and highly effective, though most patients recover well without surgery.

Final Takeaway
Trigger Finger can be painful and disruptive, but most cases respond well to splints, therapy exercises, and anti-inflammatory treatments. Surgery is rarely needed but available for severe cases.
With the right combination of support, rest, and hand care, you can restore smooth finger movement and prevent worsening.
