Carpal Tunnel Syndrome

Carpal tunnel syndrome is caused by a compressed nerve in the wrist.

Repetitive activities, such as typing on a keyboard, can cause nerve compression. There are many other causes of carpal tunnel syndrome:

• A narrow carpal tunnel (due to heredity).
• Arthritis.
• Diabetes.
• Hormone-related conditions, such as pregnancy or menopause.
• Medications, such as birth control pills or some blood pressure medications.
• Raynaud's disease, which impairs blood flow in the hands.
• Use of vibrating equipment or tools.
• Water retention due to kidney or heart disease.
• Wrist injury.

Symptoms of carpal tunnel syndrome can vary:

• Tingling, burning or numbness, especially in your thumb and index or middle fingers
• Pain or numbness that worsens with movement or after waking up
• Hand stiffness or cramping that gets better after shaking the hand or waking up in the morning
• Weakness or clumsiness of your hand

Our providers use a range of simple and minimally invasive tests to diagnose carpal tunnel syndrome:

• Tinel’s sign
• Compression test
• Electromyography (EMG)
• Imaging scans, such as an MRI or X-ray

Treating carpal tunnel syndrome involves relieving pressure on nerves in the hand and wrist. There are several ways to relieve pressure. Your orthopedic provider may recommend a variety of treatments:

• Rest and exercises
• Splinting
• Medications, including cortisone injections
• Carpal tunnel release surgery

You can lower your risk of getting carpal tunnel syndrome by taking these steps:

• Minimize repetitive hand movements.
• Alternate between activities or tasks to reduce strain.
• When using your wrists, keep them straight and let your arms and shoulders share the stress.
• Use your whole hand or both hands to pick up items.
• Avoid holding an object the same way for a long time.
• If you work in an office, adjust your desk, chair and keyboard so you are in the best possible position.
• Take breaks at least once an hour to:
  • Rest or shake your hands.
  • Massage the palms and backs of your hands.
• Do stretches to loosen the shoulders and arms before settling in to work.
• Keep your hands warm.
• Exercise regularly.
• Cut down on caffeine and smoking.
