Trigger finger makes a finger get stuck in a bent position. It may straighten suddenly with a snap. The fingers most often affected are the ring finger and the thumb, but the condition can affect any finger.
Trigger finger happens when the tendon that controls that finger can't glide smoothly in the sheath that surrounds it. This may occur if part of the tendon sheath becomes swollen or if a small lump forms on the tendon.
Symptoms
Symptoms of trigger finger may progress from mild to severe and include:
Finger stiffness, particularly in the morning.
A popping or clicking sensation as the finger moves.
Tenderness or a bump in the palm at the base of the affected finger.
Finger catching or locking in a bent position, which suddenly pops straight.

Trigger finger can affect any finger, including the thumb. More than one finger may be affected at a time, and both hands might be involved. Triggering is usually worse in the morning.
Western medicine treatments are often steroid injections which are often not effective; or surgery.
