Quick answer: Trigger finger (stenosing tenosynovitis) is a condition in which a finger or thumb catches, locks, or snaps when bending or straightening, caused by swelling around the tendon that runs into the finger. It is common, especially with repetitive gripping activities or in people with diabetes, and usually responds well to simple treatment. The appointment confirms the diagnosis, a few conditions cause similar catching, and matches treatment to severity, since mild cases and locked, stuck fingers are managed quite differently.
A finger that catches or locks partway through bending is alarming the first time it happens, and understandably so, but trigger finger is one of the more reliably treatable hand conditions, with a clear step-up ladder from splinting through injection to a quick outpatient procedure for the minority who need it. The appointment is where your specific stage gets identified, since that stage, not just the presence of catching, is what determines the right starting treatment.

Mild, Locking, or Something Else?
| Pattern | What it suggests |
|---|---|
| Finger clicks or catches but straightens on its own | Milder trigger finger, often responds to splinting alone |
| Finger locks and needs the other hand to straighten it | More significant trigger finger, usually needs injection or procedure |
| Tenderness at the base of the finger with a firm nodule you can feel | Classic trigger finger, the nodule is the swollen tendon area |
| Numbness or tingling rather than catching | May be a nerve problem (e.g. carpal tunnel) instead, needs its own assessment |
Numbness or tingling, rather than mechanical catching, points away from trigger finger and towards a nerve cause such as carpal tunnel syndrome, worth distinguishing clearly when you describe your symptoms. Straightforward trigger finger is well suited to a sports medicine or physiotherapy appointment for splinting and hand therapy, while locked or recurrent cases are typically referred to an orthopaedic surgeon or hand specialist.
What to Track and Bring
- Which finger(s) and how severe: catches and releases on its own, or needs help to straighten
- When it is worst: classically first thing in the morning, easing through the day
- Repetitive activities: gripping tools, typing, playing an instrument, or manual work, the trigger, if there is one
- Diabetes or other joint conditions: both raise the risk and are worth mentioning explicitly
- What you have tried: splinting, rest, anti-inflammatories. A appointment notebook noting which activities bring on catching helps identify a modifiable trigger
Diagnosis and the Treatment Ladder
Diagnosis is clinical, the catching pattern and a tender nodule at the base of the affected finger are usually enough, with no imaging typically needed. Treatment climbs a ladder matched to severity: splinting the finger at night for mild cases, a steroid injection for more persistent or locking cases (often effective, sometimes needing a repeat), and a short outpatient procedure (release of the tight tendon sheath) for cases that do not settle with injection. Diabetes can make trigger finger more stubborn and slightly less responsive to injection, which your doctor will factor into the plan.
Helpful for this appointment
- appointment notebook, noting which specific grip or repetitive activity precedes catching helps target both treatment and prevention
- weekly pill organiser, useful if a short anti-inflammatory course is advised alongside splinting

Questions to Ask Your Doctor
- Is this trigger finger, or could it be a nerve problem like carpal tunnel?
- How severe is my case, and does that change where we start treatment?
- Would night splinting alone be enough, or should we consider an injection?
- How effective is a steroid injection likely to be, given I have diabetes (if relevant)?
- If the injection does not help, what does the procedure involve and what is recovery like?
