Pain management health centre. Trigger finger. Trigger finger is a painful condition causing the fingers to catch or lock up when they are bent. This can also affect thumbs, called trigger thumb. Trigger finger is usually due to inflammation of tendons connecting muscles and bones in the fingers or thumbs. Tendons usually slide easily through their covering of tissue with a lubricating membrane surrounding the synovium joint.
One of the first symptoms of trigger finger is soreness at the base of the finger or thumb. The most common symptom is a painful clicking or snapping when bending or straightening the finger. This catching sensation tends to get worse after resting the finger or thumb and loosens up with movement.
