Wrist pain when moving your thumb can be caused by several issues, but a common culprit is De Quervain's tendonitis.
Understanding De Quervain's Tendonitis
De Quervain's tendonitis affects the tendons that control thumb movement. These tendons run through a sheath (a tunnel-like structure) on the thumb side of your wrist. When these tendons become inflamed or swollen, they can't glide smoothly through the sheath. This causes pain, especially when you move your thumb or wrist.
Symptoms of De Quervain's Tendonitis:
- Pain on the thumb side of your wrist.
- Pain that worsens when you move your thumb, especially when grasping or pinching objects.
- Swelling on the thumb side of your wrist.
- A "catching" or "snapping" sensation in your thumb.
The reference material states that tendons normally slide through a flexible tunnel, called a sheath, to connect and support the thumb. When the tendons swell or the sheath thickens because of pressure or inflammation, you may notice that your the inside of your wrist or your thumb hurts. This perfectly explains the pain experienced when moving the thumb in De Quervain's tendonitis.
Other Potential Causes
While De Quervain's tendonitis is a frequent cause, other conditions can also lead to wrist pain when moving your thumb. These include:
- Carpal Tunnel Syndrome: This affects the median nerve in your wrist, causing numbness, tingling, and pain in the hand and thumb.
- Fractures: A broken bone in the wrist or thumb can cause significant pain on movement.
- Arthritis: Inflammation of the joints can cause pain and stiffness, impacting thumb movement.
- Tenosynovitis: Inflammation of the tendon sheaths, which can affect the thumb.
It's crucial to consult a doctor for a proper diagnosis and treatment plan. They can determine the underlying cause of your wrist pain and recommend appropriate management strategies.
