Trigger Finger

Q Can trigger finger be completely cured? Is it treatable even in chronic cases? I am a woman in my 60s.

A. Early to moderate trigger finger can be fully cured (remission of symptoms and no recurrence) with aggressive treatment. Even in cases where the tendon nodule has grown large or the tendon structure has been deformed due to years of neglect, lock release and pain reduction can usually be achieved; however, restoring the full range of motion requires a longer time. In chronic cases, combining treatment with systemic tissue environment improvement (constitutional correction) is crucial for the prognosis.

Q I have developed trigger fingers in both hands simultaneously. Can they be treated together? I am a diabetic male in my 50s.

A. Simultaneous onset in both hands is common in patients with diabetes or rheumatism, and treatment is required for both hands. While it is possible to perform acupuncture on both hands at once, temporary decline in hand function may occur simultaneously in both hands after the procedure. Therefore, a sequential approach is often recommended: treating the dominant hand first, followed by the opposite hand 2 to 3 days later. Systemic metabolic management (blood sugar control) and constitutional correction are key prerequisites for simultaneous bilateral treatment.

Q I have both trigger finger and carpal tunnel syndrome. Can they be treated at the same time? I am a woman in my 50s.

A. It is relatively common for trigger finger and carpal tunnel syndrome to occur together in the same hand, accounting for 20–30% of cases. Both conditions can be treated with acupuncture, moxibustion, and pharmacopuncture at a Korean medicine clinic. Since the treatment sites and acupoints partially overlap, simultaneous treatment is possible in a single visit. However, if nerve compression due to carpal tunnel syndrome is severe, the treatment priority is adjusted based on the results of a nerve conduction test.

Q Are there any stretches or care methods I can do at home while undergoing treatment for trigger finger? I am a housewife in my 40s.

A. Repeating extension stretches—slowly extending your finger as far as possible, holding for 5 seconds, and then relaxing—3 to 5 times a day helps maintain tendon flexibility. Applying a warm compress (40–42 degrees Celsius) for 10 minutes before and after treatment increases local blood flow and alleviates pain. Avoid excessive hand use for 24 hours immediately after treatment, and if you have a habit of clenching your fingers tightly in bed, immobilizing them with a night splint will reduce morning locking symptoms.

Q I have trigger finger; is it okay to continue working? I am in my 30s and do a lot of computer work.

A. Ideally, you should rest your hand completely, but if that is not realistically possible, it is practical to minimize triggering movements and utilize assistive devices. Using keyboard shortcuts to reduce the number of mouse clicks, switching to a vertical mouse or trackpad that puts less strain on the fingers, and stretching your fingers for 5 minutes every hour are recommended. Reducing hand usage by more than 30% during the treatment period significantly shortens the recovery period.

Q I am afraid of the needle knife procedure. Is it safe? Is there no risk of my tendon rupturing? I am a woman in my 50s.

A. The needle knife is a special needle thicker than a standard needle and is performed without local anesthesia. When performed by a skilled Korean medicine doctor, the risk of tendon damage is very low. Safety is further enhanced by using ultrasound guidance, which allows for real-time monitoring of tendon and nerve locations and the selective dissection of only the A1 pulley. Local pain and bruising may occur for 1 to 2 days after the procedure, but they usually disappear naturally.

Q Is it okay to receive treatment at a Korean medicine clinic while taking anti-inflammatory painkillers? I am a woman in my 50s.

A. In most cases, NSAIDs (anti-inflammatory painkillers) and Korean medicine treatments can be used in combination. However, since some herbal ingredients may have anticoagulant effects, you must inform the doctor of any medications you are currently taking during your consultation. Procedures such as moxibustion and acupuncture work through different mechanisms than anti-inflammatory painkillers, making them complementary; in some cases, this allows you to maintain therapeutic effects while reducing the dosage of painkillers.

Q How long does it take to recover from trigger finger after treatment? I am a housewife in my 40s.

A. For mild to moderate cases (snapping stage), symptoms often improve significantly within 4 to 8 weeks with combined acupuncture and moxibustion treatment. If the condition has progressed to the locking stage, a treatment period of 2 to 3 months may be required, and recovery may be slower if there are underlying conditions such as diabetes. Even after treatment ends, managing triggering movements and performing self-stretching are necessary to prevent recurrence.

Q Trigger finger has recurred after treatment. What should I do to prevent repeated recurrences? I am a male in my 50s.

A. The biggest reason for recurrence is when triggering movements persist or when treatment only suppresses inflammation without reducing the thickness of the tendon sheath itself. To prevent recurrence, you must combine needle acupuncture, which physically separates tendon sheath adhesions, with thread embedding and fire acupuncture to strengthen tendon elasticity. Additionally, you must improve your work habits and make self-stretching a part of your daily routine. If you have underlying conditions such as diabetes or rheumatism, you must also manage your entire body to extend the interval between recurrences.

Q I am a housewife in my 40s, and recently I have been feeling a catching sensation when I bend and straighten my finger. Why does trigger finger occur?

A. Trigger finger occurs when inflammation develops and thickens between the finger tendon (flexor tendon) and the tendon sheath surrounding it. Repetitive hand use, occupations involving frequent gripping movements, or housework are major causes, and it is more likely to occur in individuals with diabetes or rheumatoid arthritis. If symptoms worsen, it deteriorates into a "locking" phenomenon where the finger remains bent and cannot be straightened.

Q I am a man in my 50s with diabetes who has developed trigger finger. Is it related to diabetes?

A. Due to poor blood sugar control, diabetic patients experience glycation in tendon and tendon sheath tissues, leading to reduced elasticity and rapid hypertrophy; consequently, the risk of developing trigger finger is 2 to 3 times higher than in the general population. In cases where systemic metabolic issues act as the cause in addition to simple repetitive use, blood sugar management must be maintained even during treatment to ensure a good recovery. Another characteristic of the diabetic form is that it often occurs in multiple fingers simultaneously, rather than just one.

Q Are there any foods I should avoid when I have trigger finger? I am a female office worker in my 40s.

A. Trans fats, refined sugars, and excessive alcohol can exacerbate inflammation and increase the inflammatory response of tendons, so it is advisable to reduce them as much as possible. Conversely, oily fish rich in omega-3, turmeric (curcumin), and ginger are helpful due to their anti-inflammatory effects. Vitamin C (found in vegetables and fruits) and zinc (found in nuts and seafood), which are necessary for collagen synthesis, also play a positive role in tendon recovery.

Q I am a man in my 30s working at a manufacturing factory in Dong-gu, Incheon. Is my job aggravating my trigger finger?

A. Repetitive gripping motions, the use of vibrating tools, and prolonged gripping are the most common triggering and aggravating factors for trigger finger. In particular, using vibrating tools daily leads to the accumulation of frictional heat and micro-damage within the tendon sheath. Along with treatment, it is essential to improve work practices (adjusting tool grip thickness, wearing anti-vibration gloves, and stretching during work).

Q How often should I visit the Korean medicine clinic? I am a busy office worker in my 30s.

A. During the initial intensive treatment phase, visits 2 to 3 times a week are recommended. Once symptoms improve by more than 50%, the frequency is reduced to once a week, and then transitions to maintenance care once every two weeks. The basic treatment course usually takes 4 to 8 weeks, although the locking phase may require a longer period. Since there may be localized pain for 2 to 3 days after the needle acupuncture procedure, controlling hand usage before and after the procedure enhances effectiveness.

Q I have been diagnosed with trigger finger for the first time. In what order is the treatment conducted at the Korean medicine clinic? I am a male in my 40s.

A. Upon the initial visit, we first confirm the stage of the condition and check the thickness of the tendon sheath and the presence of nodules via ultrasound evaluation. Then, we prioritize acupuncture and pharmacopuncture treatments to reduce acute inflammation. After 2 to 3 weeks, once inflammation subsides, we proceed with needle acupuncture to dissect the thickened A1 pulley. Subsequently, we promote tissue regeneration using fire acupuncture and thread embedding. In the final stage, we conclude with education on tendon strengthening exercises to prevent recurrence and a prescription of herbal medicine tailored to the patient's constitution.

Q Do I need to continue visiting the Korean medicine clinic even after the main treatment for trigger finger is finished? I am a woman in my 50s.

A. After the main treatment, receiving maintenance care at intervals of 2 to 4 weeks is effective in preventing recurrence. Regular check-ups every 3 to 6 months are recommended, especially for those with occupations involving heavy hand use or diabetes. Although maintenance care is less intense and shorter in duration than intensive treatment, it plays an important role in consistently maintaining the tendon environment in good condition.

Q I am an office worker in my 30s. I heard that getting steroid injections would solve the problem, but are there any advantages to treatment at a Korean medicine clinic?

A. While steroid injections provide rapid anti-inflammatory effects, repeated injections carry a risk of tendon weakening or rupture, and the average recurrence rate is over 50%. Treatments at Korean medicine clinics—such as moxibustion, acupuncture, and pharmacopuncture—focus on preventing recurrence and strengthening tendons by physically releasing tendon sheath adhesions and promoting tissue regeneration. The two approaches are not mutually exclusive; they are often used in combination during the acute phase, after which patients transition to Korean medical rehabilitation treatment.

Q I am a retiree in my 60s living in Dongincheon. I was recommended surgery by an orthopedic clinic, but can I avoid surgery through treatment at a Korean medicine clinic?

A. Trigger finger surgery is a simple procedure involving the incision of the A1 pulley, but it carries risks such as a long recovery period, scarring, and tendon instability. Many cases of mild to moderate trigger finger before the locking stage have been reported to recover without surgery through combined treatment with moxibustion, acupuncture, and pharmacopuncture. However, if the condition has progressed to tendon rupture or complete fixation flexion contracture, surgery may be unavoidable, so it is important to determine the course of treatment after an accurate assessment of the condition.
