Trigger finger is common if you spend a lot of time typing on a computer or working with your hands. It occurs when your finger gets stuck in a painful bent position and is unable to straighten on its own.

In addition to being painful, trigger finger can prevent you from being able to perform your daily duties. After all, you need your hands for just about everything.

If this happens to you often, read on. This guide will explain what causes trigger finger and helpful tips to relieve the pain and get your mobility back.

What Is Trigger Finger?

In trigger finger, the affected finger, which is often the ring finger or the thumb (though it can affect any finger) – is unable to straighten on its own. There is usually pain at the base of the finger in the palm. 

When you have trigger finger, also known as stenosing tenosynovitis, the “pulley” at the base of your finger and your tendon sheath are not working optimally. This causes your flexor tendon to “catch” in its sheath. Your finger gets stuck in a bent position, unable to straighten on its own. This condition can be very painful.

Causes

Spending a lot of time with your fingers in a bent position may trigger the condition.

There are three ways the flexor tendon can catch and be unable to glide normally in its sheath:  

  1. The tendon swells, causing it to be larger than usual 
  2. The tendon sheath is inflamed, causing it to be too narrow for the tendon 
  3. The A1 pulley is swollen or thickened, making it harder for the tendon to glide

People in occupations or who perform activities involving repetitive forceful movements, such as farmers, musicians, construction workers, and housekeepers, can develop this condition. Trigger finger typically affects adults in their 40s or older. It occurs in women more often than men and about 2% of the general population.

In the population of those with diabetes, the incidence increases to about 17%. Other risk factors for developing trigger fingers include conditions that cause inflammation and affect the joints, such as rheumatoid arthritis, gout, amyloidosis, an underactive thyroid, carpal tunnel syndrome, Dupuytren’s contracture, and De Quervain’s disease. This is why one of the proposed treatments includes anti-inflammatory remedies.

In Traditional Chinese Medicine (TCM), trigger finger is categorized as part of a larger category of conditions referred to as tendon paralysis. “Pathologically, this condition is associated with blocked meridians, poor Qi and Blood flow, and Qi Stagnation caused by Blood Stasis,” explains TCM Physician Ignatius Ooi.

How To Treat Trigger Finger

Finger stretches and exercises may help strengthen the surrounding area to reduce symptoms.

Fortunately, the condition is highly treatable. Treatments focus on releasing the stuck tendon and addressing the pain associated with the issue. In TCM, the focus is on restoring the optimal flow of qi through the body’s meridians as well as enhancing the body’s own ability to heal the condition. 

Rest 

This may be obvious, but at the first sign of dull pain and decreased range of motion signaling the possibility of trigger finger, make sure to cease the activity and let your fingers rest.

This may be difficult for people whose occupations depend on their ability to use their fingers. But not resting will only make the condition worse, leading to more severe damage that could affect your livelihood permanently.

Wear a splint 

The main complaint of trigger finger is the inability to straighten the bent finger. This is especially after a long period of resting, such as when sleeping at night. Your doctor may recommend putting on a finger splint that prevents the compromised flexor tendon from bending your finger throughout the night.

Keep in mind that when you wake up in the morning and remove the splint, it may take some time to get your finger to move again. Take it slow. Gently and lightly massage the base of the finger to slowly loosen the joint and muscles. 

Anti-inflammatory medicine 

One way to find some relief is to reduce the swelling and reduce the pain response by using painkillers. For relatively immediate pain relief, you can take non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen.

If this still doesn’t help much, a corticosteroid injection may help. This is a more direct and slightly invasive treatment due to the injection at the sight of the inflammation.

It is usually effective at reducing swelling, though it could take a few days for a positive effect to take place. Work with a trained physician, but note that if you have diabetes, you may also need to work with your doctor to monitor your blood sure levels. Otherwise, you might experience a short-term rise in blood sugar.

Acupressure

The TCM approach to trigger finger is focused on restoring the flow of Qi by optimizing the meridians. This removes Blood Stasis and Qi Stagnation.

Consider doing some acupressure on yourself at the first sign of stiffening and the sensation of catching or locking in the tendon. Physician Ooi shares the pressure points that can help: 

  • Qu Chi (LI11)
  • Yang Chi (SJ-TE4) 
  • Pian Li (LI6) 
  • He Gu (LI4) 
  • Lie Que (LU7) 
  • Thenar: (the fleshy muscle at the base of the thumb) 
  • Ashi point: “Ashi” is similar in concept to “trigger points” that refer to the tender points in the affected area 

“Rub the point repeatedly with the thumb or thenar eminence (the ball of the thumb), until the affected spot feels warm. Spend 15 to 20 minutes for each treatment once a day. The amount of stimulation should be determined by the person’s preference or condition. A ten-minute warm compress can follow the massage,” Physician Ooi further instructs. 

TCM Herbs 

TCM treatments also focus on helping the body heal itself. One of the ways to do this is through herbal medicine. Physician Ooi shares a quick recipe using coix seeds (Yi Yi Ren), commonly known as Job’s Tears, to remove Stasis and improve blood circulation:  

  1. Add an appropriate amount of water to 50 g of coix seeds and 50 g of rice. 
  2. Boil until it turns into porridge. 
  3. Take one small bowl every morning and night for about two weeks and monitor progress. 

You may also consider other potential herbs that can help strengthen the body, such as Acanthopanax notoginseng found in Tian Qi pills. It is usually taken twice per day after meals. As always, work with a licensed and experienced TCM practitioner rather than self-medicating. 

Surgery 

If other treatments are ineffective and the severity of your condition worsens, talk to your doctor about the possibility of surgery. There are two types of surgery commonly used to treat severe trigger finger.

Open surgery, called Tenolysis surgery, is an incision at the base of the affected finger. It essentially releases the A1 pulley to allow the tendon to free up. It requires healing time due to the incision.

Another type of surgery is percutaneous surgery. It uses a needle that punctures through the skin and ligament to release the tendon at the same A1 pulley location. This is aided by ultrasound imaging that enables the surgeon to find the right location.

If surgery is your last resort, work with your doctor and healthcare provider to determine the most suitable type for your condition. 

Losing the ability to control movement in your finger is not only frustrating but also painful. Fortunately, trigger finger treatments are relatively straightforward and usually effective.
