Signs and symptoms of trigger finger may progress from mild to severe and include:
- Finger stiffness, particularly in the morning
- A popping or clicking sensation as you move your finger
- Tenderness or a bump (nodule) in the palm at the base of the affected finger
- Finger catching or locking in a bent position, which suddenly pops straight
- Finger locked in a bent position, which you are unable to straighten
Trigger finger more commonly affects your thumb or your middle or ring finger. More than one finger may be affected at a time, and both hands might be involved. Triggering is usually more pronounced in the morning, while firmly grasping an object or when straightening your finger.
When to see a doctor
If you have any stiffness or catching in a finger joint, bring it to the attention of your doctor so that he or she may review your symptoms and perform a physical evaluation of your hand. If your finger joint is hot and inflamed, seek immediate medical care because these signs indicate a possible infection.
