The human hand is one of our most versatile tools, enabling us to perform a wide range of tasks, from complex activities like playing the piano to basic daily tasks like gripping a cup of coffee. But what happens when this valuable tool starts to malfunction? Enter trigger finger, a condition that can cause pain, stiffness, and even locking of the fingers or thumb.
Suppose you’ve been experiencing discomfort in your hands or noticed a snapping sensation as you move your fingers. In that case, this guide will walk you through everything you need to know about trigger finger, from its causes and symptoms to diagnosis and treatment options.
What Is Trigger Finger?
Trigger finger, medically known as stenosing tenosynovitis, is a condition where one of your fingers or thumbs gets stuck in a bent position. It may straighten with a snap, much like releasing the trigger of a gun. This is caused by the narrowing of the sheath that surrounds the flexor tendons in your fingers, leading to inflammation and restricted movement.
Without treatment, trigger finger can significantly affect your ability to perform day-to-day activities, such as typing, gripping objects, or holding a pen. But fortunately, there are effective solutions available to manage and treat this condition.
What Causes Trigger Finger?
Trigger finger is often linked to repetitive or strenuous hand movements, but several other factors can also come into play. Understanding its causes can help you identify habits or conditions that may contribute to the condition.
1. Repetitive Hand Movements
Activities like gripping tools, playing musical instruments, or frequently texting can strain the tendons in your hands, leading to inflammation.
2. Occupational or Recreational Strain
Jobs or hobbies that involve repetitive gripping—including heavy tool use, gardening, and rock climbing—are common triggers for this condition.
3. Underlying Health Conditions
Certain medical issues, such as diabetes, rheumatoid arthritis, or gout, increase your risk. These conditions can cause inflammation in the tendons, making them prone to irritation.
4. Injuries
Trauma to the hand or fingers can inflame the tendon sheath, triggering symptoms over time.
Identifying these root causes early can help you take the steps necessary to prevent or manage trigger finger effectively.
Recognising the Symptoms of Trigger Finger
Spotting the symptoms of trigger finger early can make a significant difference in managing and treating the condition before it worsens. Here’s what to look out for:
Stiffness or Locking
Difficulty moving your finger or thumb, especially first thing in the morning.
Pain and Tenderness
Pain at the base of the affected finger (often in the palm) is a common complaint.
Clicking or Snapping Sensation
A noticeable “pop” when bending or straightening your finger is a hallmark of trigger finger.
Swelling or Lump Formation
Some people notice swelling or a tender nodule at the base of the affected finger.
Permanent Locking (Severe Cases)
When untreated, the affected finger may become stuck in a bent position, limiting mobility entirely.
If you notice these symptoms, it’s time to consider a diagnosis before the condition progresses.
How Is Trigger Finger Diagnosed?
At clinics like RAD Clinics, diagnosing trigger finger involves a straightforward process that includes a physical examination and, in some cases, imaging.
Physical Examination
Your specialist will ask about your symptoms and perform a physical examination. They will look for common signs such as tenderness or any locking/clicking sensation during finger movement.
Ultrasound Imaging
For a more accurate diagnosis, ultrasound technology can confirm inflammation or abnormalities in the tendon sheath. This ensures that the clinician can recommend the most effective treatment plan.
By diagnosing trigger finger early, you can avoid surgery and instead opt for stress-free, minimally invasive treatments.
Treatment Options for Trigger Finger
Trigger finger may sound like a painful and debilitating condition, but the good news is that it’s highly treatable. At RAD Clinics, we offer a range of treatment options, from rest and lifestyle changes to advanced medical interventions.
Non-Invasive Treatments
1. Rest and Conservative Care
The first line of treatment is often to rest the affected hand. Here are some steps you can take at home:
Avoid repetitive hand movements.
Use splints or braces to keep the affected finger straight.
Apply ice packs to reduce inflammation.
2. Anti-Inflammatory Medications
Over-the-counter anti-inflammatory medications, such as ibuprofen, can help reduce swelling and ease pain.
Ultrasound-Guided Cortisone Injections
One of the most effective treatments for trigger finger is ultrasound-guided cortisone injections, offered at clinics like RAD Clinics. Here’s why this minimally invasive solution is gaining popularity:
Precision: The ultrasound ensures the cortisone is delivered directly into the inflamed tendon sheath.
Quick Results: Many patients report significant symptom relief within a few days to weeks.
Non-Surgical Option: This treatment avoids the risks and downtime associated with surgery.
Minimised Pain: Local anaesthetic is used, making the procedure highly tolerable.
How It Works: During the procedure, your doctor will first perform an ultrasound scan to identify the inflamed area. They’ll then use this live imaging to administer the cortisone injection with pinpoint accuracy.
RAD Clinics prides itself on offering this technology, ensuring patients experience safe, effective, and professional care.
When to Seek Medical Treatment
If your symptoms persist despite rest and self-care, or if they start to interfere with daily tasks, medical treatment should be your next step. You must seek treatment if:
Your finger frequently gets stuck in a bent position.
Pain and tenderness disrupt work or hobbies.
Symptoms don’t improve with home remedies or over-the-counter medications.
The earlier you seek medical advice, the more treatment options you’ll have, which could prevent the condition from escalating to the point where surgery becomes necessary.

Trigger finger doesn’t have to limit your lifestyle. Whether you’re experiencing mild discomfort or severe symptoms, identifying the condition early and choosing the right treatment is key to regaining full mobility in your hands.
