Morning finger catching and difficulty straightening: trigger finger
A finger that clicks or catches in the morning, with pain at its base on the palm side, may have trigger finger. A narrowed tendon passage can interfere with smooth movement, but arthritis and injury can feel similar. Repeated locking deserves assessment; do not force the finger straight or repeatedly provoke clicking.
The tendon that bends the finger passes beneath ring-shaped tissue on the palm side. Thickening of the tendon or this tissue can narrow the passage, causing catching, clicking or locking in a bent position. Pressure where the finger meets the palm may hurt, and a small lump may be felt.
Stiffness and catching can be more noticeable in the morning or after rest and ease somewhat with gentle movement. Repeated forceful gripping or pinching may be associated, although there may be no clear trigger. Diabetes and rheumatoid arthritis are also considered.

Similar symptoms can have different causes
Finger arthritis may cause pain and swelling within the joint and restricted movement. Pain at the palm-side base of the finger and catching at a particular point are clues to trigger finger.
Dupuytren contracture can cause a firm cord in the palm and gradual bending of the finger, rather than brief clicking. Swelling and difficulty moving after injury may reflect joint or tendon damage. Symptoms alone do not establish the cause.
Treatment follow-up considers pain, frequency of locking, ease of straightening and difficulty using the hand in daily life.
Inoue and colleagues' small 2016 observational study treated 19 fingers in 15 patients with trigger finger with up to five acupuncture sessions. Pain and triggering scores improved in the before-and-after comparison.
Kazal and Themer's 2023 case report described one 58-year-old man with over a year of pain and locking of the left ring finger. After four electroacupuncture treatments over approximately one and a half months, he reported resolution of pain and triggering.
These observations inform discussion, while treatment is selected according to the finger's condition and adjusted as pain, movement and everyday function change. Reducing repetitive strain on the hand remains part of management.
Reduce forceful gripping or pinching that provokes symptoms and avoid carrying heavy objects hooked over the fingers. Take breaks when gripping the same tool for a long time.
Move gently within a pain-free range. Do not repeatedly click the finger to test it or force it straight. If overnight bending leads to morning difficulty, discuss a suitable splint after examination.
At Namugeuneul Korean Medicine Clinic, we assess the painful area, the actual catching movement and usual hand-use habits. Recurrent morning difficulty straightening the finger can be discussed alongside suitable treatment and activity adjustments.
