Trigger Finger Corticosteroid Injection With and Without Local Anesthetic

The treatment of trigger finger involves an injection of corticosteroid. Corticosteroid treats the underlying inflammatory pathology. Some surgeons add lidocaine with epinephrine as a local anesthetic with the injection. Lidocaine with epinephrine is associated with a burning sensation and may be the primary pain associated with the injection. We hypothesize that a corticosteroid injection without lidocaine with epinephrine will be less painful, and equally effective in treating trigger finger
