“It catches, and then it sort of pops.” That’s usually how patients describe it, often holding up the offending finger and demonstrating the movement themselves, as if it’s a party trick rather than a genuine problem. It isn’t a party trick. Trigger finger can be surprisingly painful, and for some people it becomes disruptive enough that everyday tasks, doing up buttons, holding a cup, typing, become a daily irritation.
Trigger finger is one of those conditions that patients often live with for far too long before seeking help, partly because it tends to come on gradually and partly because it’s easy to assume it will simply go away. Sometimes it does settle with time and a few sensible changes. Often it doesn’t, and the good news is that once you understand what’s actually happening in the finger, the treatment options are straightforward and generally very effective.

What’s Actually Happening In The Finger
Trigger finger, known medically as stenosing tenosynovitis, happens at the base of the finger, right where it meets the palm. Each finger has a tendon that runs from the forearm muscles, through the palm, and into the finger, allowing it to bend. That tendon passes through a series of small tunnels, or pulleys, that hold it close to the bone and keep the movement smooth and efficient.
The first of these pulleys, called the A1 pulley, sits at the base of the finger and is the one that usually causes the trouble. If the tendon becomes irritated and swells, or if a small nodule develops on it, the tendon can no longer glide freely through the pulley. Instead, it catches as it tries to pass through, and the finger gets stuck in a bent position. With enough force, it releases suddenly, producing that characteristic snap or pop as the tendon jerks through the narrowed tunnel. In more advanced cases, the finger can lock completely and needs to be straightened manually with the other hand.
We’re often asked what causes this in the first place, and the honest answer is that in many cases there isn’t one single obvious trigger. Repetitive gripping activities, whether that’s manual work, certain sports, or simply a hobby that involves a lot of hand use, can contribute. It’s also considerably more common in women, particularly around and after the menopause, and tends to appear most often in the 40s to 60s age group. Diabetes is a significant factor too. Patients with diabetes are more likely to develop trigger finger, sometimes in several fingers at once, and it can be more stubborn to treat. Rheumatoid arthritis, gout and underactive thyroid function are also associated with a higher risk. In a good number of patients, though, there’s no clear underlying cause at all. It simply happens.
Recognising The Signs
Trigger finger usually announces itself gradually. Stiffness first thing in the morning is a common early sign, often easing off as the hand is used through the day. A tender lump can sometimes be felt at the base of the affected finger, right in the palm, and this is usually the thickened section of tendon or the pulley itself. As things progress, the catching or locking sensation becomes more obvious, and it can affect the thumb just as easily as any of the fingers, in which case it’s referred to as trigger thumb.
The severity varies enormously between patients. Some notice nothing more than an occasional click that doesn’t bother them much. Others find the finger locking in a bent position multiple times a day, which understandably becomes both uncomfortable and frustrating. Diagnosis is usually straightforward and doesn’t typically need scans or blood tests. A careful history and an examination of the hand, feeling for the nodule and watching the finger move, is generally enough to confirm what’s going on.
What Can Be Done About It
Treatment tends to follow a logical order, starting with the simplest measures and moving on if these don’t give enough improvement.
For mild or early cases, resting the hand and modifying activities that involve repeated gripping can allow the irritation to settle on its own. A splint worn at night, which keeps the base of the finger in a slightly extended position, can also help by resting the tendon while it heals, and some patients find this alone is enough.
When symptoms are more persistent, a steroid injection directly into the tendon sheath is usually the next step, and in our experience it’s a genuinely effective treatment for a lot of patients. It reduces the swelling around the tendon, allowing it to glide through the pulley normally again. Relief often begins within a week or two, and a good proportion of patients find that a single injection resolves the problem completely, or at least for a good long stretch. We’re always honest that it doesn’t work for everyone, and that patients with diabetes in particular sometimes need a repeat injection or find the response less complete, but it remains a sensible and low risk option worth trying before considering surgery.
When Surgery Is The Right Answer
For fingers that don’t settle with splinting or injections, or for those that are locking persistently and affecting daily function, a small surgical release of the A1 pulley is a very reliable solution. This can often be done under local anaesthetic, sometimes through a tiny incision and sometimes using a needle technique that avoids a cut altogether, and the procedure itself takes only a matter of minutes. Most patients are moving the finger normally again within a few weeks, and the success rate is high. We don’t view surgery as a last resort to be feared, more as the definitive answer for a finger that hasn’t responded to the simpler options.
Making The Right Choice For You
There’s no single correct pathway for every patient, and we think it’s important to say so. How long you’ve had symptoms, how much they’re interfering with your daily life, whether other fingers are involved, and whether you have diabetes or another condition that affects healing, all shape what we’d recommend. Someone with a mild, occasional click who mostly wants reassurance is in a very different position to someone whose finger locks shut several times a day and who needs their hands for work.
What To Expect At A Consultation
We’ll begin by asking about your symptoms, how long they’ve been going on, what makes them worse, and how much they’re bothering you day to day. A hand examination follows, checking the movement of the finger and feeling for the characteristic nodule at its base. In the vast majority of cases, no further tests are needed before we can talk through the options and agree on a sensible plan together.
If a finger has started catching, clicking or locking, and it’s beginning to get in the way of ordinary life, do get in touch with the clinic. It’s a common problem with a very good outlook, and there’s usually a clear and fairly quick way to sort it out.
