Trigger finger: symptoms, assessment and treatment options

What is trigger finger?

Does a finger click, catch or stay bent when you try to straighten it? Trigger finger, also called stenosing tenosynovitis, can affect a finger or thumb. A bending tendon catches as it passes through a narrowed supporting band, usually the A1 pulley near the base of the digit. Assessment helps establish whether this explains your symptoms. [4]

Symptoms and risk factors

Common symptoms include tenderness on the palm side, clicking or catching during movement, morning stiffness and episodes of locking. Symptoms may make gripping tools, preparing food or other daily tasks uncomfortable. Hand use can aggravate symptoms, but this does not prove work or exercise caused the condition. Rheumatoid arthritis is another recognised association. [6]

Often there is no single identifiable cause. Diabetes increases the likelihood of developing trigger finger: a large long-term cohort found an association even after accounting for several other factors. Having diabetes does not mean every painful or stiff finger is trigger finger, so the diagnosis still needs checking. [3]

How can physiotherapy help?

Assessment considers symptom history, previous injury, relevant health conditions, tenderness and finger movement. Trigger finger is usually identified clinically; further investigation may be considered if the presentation is unclear. Dupuytren’s contracture, tendon injury and infection can also restrict movement and require different care. A physiotherapist can assess function and help coordinate referral when the findings do not fit a straightforward trigger finger presentation. [4]

Treatment options and what the evidence says

Reducing or adapting activities that repeatedly provoke painful catching may help. Some mild cases improve without a procedure. This is usually a discussion about modifying hand use, rather than stopping all activity. [6]

A suitably fitted splint may reduce triggering and pain. A systematic review published online in 2025 found encouraging short-term results, but studies used different splints, schedules and additional therapies. Evidence about longer-term recurrence remains limited. Splint selection, fit and wearing time should be individualised and reviewed; there is no single online splinting schedule suitable for everyone. [1]

One randomised trial found no clinically important differences in pain or hand function between splinting, corticosteroid injection, or their combination over one year. However, it excluded several coexisting hand conditions, so its findings do not apply equally to everyone. Exercises or hands-on treatment are not guaranteed to stop locking; ongoing symptoms need reassessment. [2] [1]

When medical review matters

Persistent pain, recurrent locking or difficulty with daily activities warrants review. A GP or hand specialist can discuss corticosteroid injection, its risks and the possibility of recurrence. Surgical release may be considered when symptoms persist despite appropriate care, or the digit stays locked. Do not force a locked finger straight; arrange prompt assessment. A treatment decision should weigh the benefits, risks and alternatives against how much the symptoms affect you. Surgery also has risks, including infection, stiffness, numbness and scar tenderness. A specialist can explain these before you decide, rather than treating surgery as an automatic next step. [7]

Seek urgent medical assessment for rapidly worsening pain with redness or swelling, especially after a cut or puncture, or if straightening the finger is very painful. A tendon-sheath infection can resemble other finger problems and needs urgent treatment rather than routine physiotherapy. [5]
