Trigger Finger Explained: Causes, Symptoms & Physiotherapy Treatment

Trigger finger is a painful hand condition that causes a finger or thumb to catch, lock, or snap when you try to straighten it.
It can make simple daily tasks like gripping, typing, or holding objects difficult and uncomfortable.

At Ace Physio Sports Singapore, we provide effective, non-surgical physiotherapy treatment for trigger finger to reduce pain, restore smooth finger movement, and prevent recurrence.

What Is Trigger Finger?

Trigger finger, medically known as stenosing tenosynovitis, occurs when the tendon that bends your finger becomes irritated or inflamed.
This inflammation makes it difficult for the tendon to glide smoothly through its surrounding sheath, causing the finger to catch or lock.

Common Causes of Trigger Finger

• Repetitive gripping or hand use
• Prolonged use of tools, phones, or keyboards
• Inflammation of finger tendons
• Diabetes or rheumatoid arthritis
• Previous hand or wrist injury

Common Symptoms of Trigger Finger

• Finger stiffness, especially in the morning
• Clicking or popping sensation when moving the finger
• Finger locking in a bent position
• Pain at the base of the finger or thumb
• A tender lump in the palm
