Trigger finger is a painful condition that affects the tendons in the fingers or thumb. It causes one or more
fingers to snap or lock when the hands are opened or closed. A trigger finger is difficult to straighten
out. While the causes of trigger finger are unknown, it is thought that inflammation causes the tendon
and tendon sheath to swell, resulting in the condition.
Oral medications that help fight inflammation include naproxen, ibuprofen and diclofenac. For the fastest and most effective treatment, local cortisone injections are administered into the tendon sheath around the affected tendon to reduce inflammation. In cases where none of the above treatments work, surgery may be necessary.
