Symptoms
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 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 more pronounced in the morning, while firmly grasping an object or when straightening your finger.
When to see a doctor
Seek immediate medical care if your finger joint is hot and inflamed, as these signs may indicate an infection.
If you have any stiffness, catching, numbness or pain in a finger joint, or if you can't straighten or bend a finger, make an appointment with your doctor.
