Rest the affected finger and avoid repetitive gripping or forceful hand use
Wear a splint, especially at night, to keep the finger straight
Apply ice for 10–15 minutes at a time to reduce pain and swelling
Use over-the-counter pain relievers such as ibuprofen or acetaminophen if appropriate
Perform gentle finger stretching and range-of-motion exercises if tolerated
Modify activities to reduce strain on the tendon
Consider corticosteroid injection from a healthcare professional
Seek hand therapy or occupational therapy if symptoms persist
Consider surgery if the finger locks frequently or other treatments fail
See a doctor if pain, stiffness, or locking continues or worsens
