De Quervain's tenosynovitis

What it is

De Quervain's is irritation of the tendons on the thumb side of the wrist, where they run through a tight tunnel. It causes pain when you use the thumb and wrist, and is common in new parents from lifting a baby.

Common symptoms

• Pain on the thumb side of the wrist, worse with gripping or lifting
• Pain when turning the wrist or making a fist with the thumb tucked in
• Swelling or a tender spot at the wrist
• A catching feeling with thumb movement

What can help

• A thumb-and-wrist splint to rest the tendons
• Adjusting how you lift and hold things
• Topical or simple anti-inflammatories
• Hand therapy

Where an injection fits

A corticosteroid injection into the tendon tunnel is an effective first treatment and settles symptoms for most people, sometimes needing a second injection. A splint is often used alongside it. If symptoms persist, a minor surgical release is an option.
