What is trigger finger?
Trigger finger is a condition that affects the tendons that bend the fingers and thumb. These tendons run in snug tunnels. Sometimes the tendons become irritated, making passage through the tunnels difficult. This often causes pain and can cause a popping or catching sensation when trying to flex and extend the fingers. In severe cases, the digit may become stuck in a bent position. In mild cases involving only occasional pain and catching, rest and anti-inflammatories may relieve the problem. If these measures are not helpful, seek medical treatment. Trigger finger can often be treated successfully with a steroid injection. In some cases, an outpatient surgery may be required to open the tight tunnel and allow the tendon to glide smoothly.
