Trigger Finger
A finger that catches and then snaps straight is a tendon size problem, and it is very treatable.
Overview
What It Is
Trigger finger occurs when a flexor tendon thickens, or its surrounding pulley narrows, so the tendon no longer glides smoothly. The finger catches as it straightens and then releases with a snap. In more advanced cases it locks bent and has to be straightened with the other hand. It is considerably more common in diabetes.

Where the Problem Is
The tendon catches on a pulley at the base of the finger. A tender nodule is felt in the palm, which is where the pain sits even though the finger is what catches.
Symptoms
How It Tends to Feel
These are the features that point towards this diagnosis rather than another:
Catching or Clicking
As the finger straightens, often worst first thing in the morning.
Locking
The finger sticking bent and needing to be released manually.
A Tender Nodule
Palpable in the palm at the base of the affected finger.
Morning Stiffness
Characteristically worse on waking and easing with use.
Pain in the Palm
Rather than in the finger itself, which surprises people.
Multiple Fingers
Common, particularly in diabetes.
Causes & Risk Factors
What Drives It
The usual contributors, in rough order of how often they turn out to matter:
Diabetes
A strong association, and trigger finger is often more stubborn in diabetes.
Repetitive Gripping
Particularly with tools or sustained forceful grip.
Age and Sex
More common in women, typically in the fifth and sixth decades.
Other Conditions
Rheumatoid arthritis, hypothyroidism and Dupuytren’s are all associated.

Treatment is built around what the assessment finds, but generally follows this shape:
When to Seek Help
Red Flags — Don’t Ignore These
Most presentations are straightforward. These features are the exceptions, and warrant prompt assessment:
⚠ Seek Medical Advice If You Notice
- A finger locked bent that cannot be straightened at all
- Redness, heat and swelling with fever — infection needs urgent assessment
- Numbness in the finger
- Rapid onset in multiple fingers with general joint swelling
If any of these apply, contact your GP or seek urgent medical care rather than waiting for a physiotherapy appointment.
Common Questions
Frequently Asked Questions
Will it go away on its own?
Some early cases settle with splinting and load modification. Established triggering usually needs injection or, less often, surgery.
Why is the pain in my palm?
Because that is where the tendon is catching on the pulley. The finger is where you feel the mechanical symptom, but the problem is at the base.
Does diabetes make a difference?
Yes. It is several times more common in diabetes, more likely to affect multiple fingers, and less responsive to injection.
Not Sure If This Is What You Have?
An assessment will tell you what is actually going on and what to do about it. I see everyone myself, and you will leave with a plan rather than a leaflet.
