Carpal Tunnel Syndrome
When Tingling and Numbness in the Hand Don’t Go Away
Carpal tunnel syndrome happens when the median nerve, which runs through the wrist, is compressed. This can cause tingling, numbness, or weakness in the hand and fingers.
Why Carpal Tunnel Syndrome Happens
The wrist has a narrow passageway called the carpal tunnel, where nerves and tendons pass through. When this tunnel becomes narrowed or irritated, the median nerve is squeezed, leading to symptoms in the thumb, index, middle, and part of the ring finger.
Common Causes and Risk Factors
Carpal tunnel syndrome can develop gradually due to:
- Repetitive hand or wrist use: typing, sewing, or factory work
- Inflammation: from arthritis or swelling of tendons
- Hormonal changes: pregnancy or menopause increasing fluid retention
- Medical conditions: diabetes, thyroid disease, or rheumatoid arthritis
- Anatomical factors: naturally smaller carpal tunnel size
Symptoms That Point to Carpal Tunnel Syndrome
Typical signs include:
- Tingling or numbness in the thumb, index, middle, or ring finger
- Hand weakness, especially when gripping objects
- Pain that worsens at night or after repetitive activity
- “Shaking out” the hand for relief
- In advanced cases, muscle wasting at the base of the thumb
How Doctors Diagnose Carpal Tunnel Syndrome
A proper diagnosis ensures treatment is targeted. Assessment may involve:
- Physical examination: testing sensation, grip strength, and wrist flexibility
- Nerve conduction studies: to measure how well electrical signals travel
- Imaging (ultrasound or MRI): in selected cases to check structures in the wrist
Treatment Options for Carpal Tunnel Syndrome
Treatment depends on severity and duration of symptoms:
- Lifestyle adjustments: avoiding repetitive strain, ergonomic changes
- Wrist splints: especially worn at night to relieve pressure
- Medications: to reduce inflammation and pain
- Injections: corticosteroid injections to calm swelling in the tunnel
- Surgery: carpal tunnel release may be recommended for severe or persistent cases
Living with Carpal Tunnel Syndrome
Early recognition is important, untreated compression can lead to permanent nerve damage. Simple steps like taking breaks from repetitive hand use, stretching, and maintaining good wrist posture can help reduce symptoms.
Frequently Asked Questions (FAQ)
1. Is carpal tunnel syndrome only caused by typing?
No. While repetitive hand use can contribute, medical conditions like diabetes or arthritis, as well as pregnancy, can also trigger it.
2. Can carpal tunnel go away on its own?
Mild symptoms may improve with rest, splinting, and lifestyle changes. Persistent or worsening symptoms often need medical treatment.
3. How long should I try splinting before considering other treatments?
If symptoms don’t improve after several weeks of splinting and lifestyle changes, it’s best to consult a doctor for further options.
4. Is surgery always required?
Not always. Many cases are managed non-surgically. Surgery is considered if symptoms are severe, long-lasting, or not responding to other care.
5. What happens if carpal tunnel is left untreated?
Severe, untreated cases can lead to permanent numbness, weakness, or loss of hand function.
