Trigger finger is a common disorder of the hand which causes painful snapping or locking of the fingers or thumb.
Trigger finger is a condition where a patient feels pain or discomfort when trying to straighten or bend their finger/thumb. Sometimes the finger may become ‘locked’ or ‘stuck’ when swelling of the tendon sheath occurs. This swelling can be associated with diabetes, rheumatoid arthritis, or even golf.
