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 to 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
Modify activities to reduce strain on the tendon
See a doctor for a corticosteroid injection if symptoms persist
Consider hand therapy for guided exercises and splinting
Seek medical evaluation if the finger locks, worsens, or does not improve
Consider surgical release if other treatments do not work
