Best treatment for thumb tendon sheath inflammation

De Quervain's tenosynovitis, also known as stenosing tenosynovitis of the radial styloid, commonly occurs in individuals who frequently use their hands. This condition is usually caused by repetitive thumb movements leading to pressure and inflammation of the tendon sheath. The optimal treatment typically includes the following aspects: 1. Rest and ice application: Reduce thumb activity and avoid repetitive wrist and thumb movements. Apply ice to the painful area for 15-20 minutes multiple times daily to help reduce swelling and pain. 2. Physical therapy: Gentle stretching and strengthening exercises can help improve the flexibility and strength of the tendon sheath. A professional physical therapist can guide appropriate exercises. 3. Wrist splints or braces: Wearing specially designed wrist splints or braces, especially at night, can help limit wrist and thumb movement, promoting healing. 4. Corticosteroid injections: If other methods are ineffective, doctors may recommend injecting corticosteroids into the affected tendon sheath to reduce inflammation. 5. Surgical treatment: In rare cases where conservative treatments fail and symptoms persist, surgery may be required to open the tendon sheath and relieve pressure. In daily life, try to avoid gripping heavy objects and performing repetitive hand movements. If symptoms persist or worsen, seek medical attention promptly.
