Carpal Tunnel Syndrome: Causes, Symptoms, Diagnosis & Treatment for Wrist Pain and Finger Numbness- By Dr. Balaraju Naidu, Robotic Orthopedic Surgeon, ONUS Robotic Hospitals

Introduction

Do you often experience wrist pain, tingling in your fingers, or numbness in your hand, especially during the night or while using your phone, computer, or driving?

These symptoms may be caused by Carpal Tunnel Syndrome (CTS), one of the most common nerve compression disorders affecting the hand and wrist.

Carpal Tunnel Syndrome develops when the median nerve, which passes through a narrow tunnel in the wrist, becomes compressed. If left untreated, the condition can lead to persistent pain, weakness, and difficulty performing everyday activities.

According to Dr. Balaraju Naidu, Robotic Orthopedic Surgeon at ONUS Robotic Hospitals, early diagnosis and timely treatment can help relieve symptoms and prevent permanent nerve damage.

What is Carpal Tunnel Syndrome?

The carpal tunnel is a narrow passage in the wrist formed by bones and ligaments.

Inside this tunnel pass:

The Median Nerve
Flexor tendons that help move the fingers

When swelling or pressure develops within the tunnel, the median nerve becomes compressed, resulting in pain, tingling, numbness, and weakness in the hand.

What Causes Carpal Tunnel Syndrome?

Several medical conditions and wrist problems can increase pressure on the median nerve.

Common causes include:

Post-pregnancy swelling
Thyroid disorders (Hypothyroidism)
Being overweight or obese
Wrist swelling due to inflammation
Previous wrist fractures
Distal radius fracture malunion
Repetitive hand and wrist movements
Diabetes
Rheumatoid arthritis
Fluid retention

Sometimes, more than one factor may contribute to the condition.

Who is at Higher Risk?

Carpal Tunnel Syndrome is more common in:

Women
Pregnant or recently delivered mothers
People with thyroid disease
Diabetic patients
Individuals who perform repetitive wrist movements
Computer professionals
Office workers
Tailors
Factory workers
People using vibrating tools

Early evaluation is especially important for individuals with these risk factors.

Symptoms of Carpal Tunnel Syndrome

Symptoms usually develop gradually and may worsen over time.

Common symptoms include:

Wrist pain
Tingling sensation in the thumb, index, middle, and part of the ring finger
Numbness in the hand
Index finger numbness
Burning sensation in the fingers
Weak grip strength
Difficulty holding objects
Dropping items frequently
Night-time hand numbness
Pain that may extend to the forearm

Ignoring these symptoms may lead to permanent nerve damage.

Why Does It Feel Worse at Night?

Many patients notice increased numbness and tingling during sleep because the wrist often bends while resting, increasing pressure on the median nerve.

Shaking the hand may temporarily relieve the symptoms.

How is Carpal Tunnel Syndrome Diagnosed?

An orthopedic specialist will evaluate your symptoms through:

Detailed medical history
Physical examination
Wrist assessment
Nerve function tests
X-rays (if fracture or arthritis is suspected)
Nerve Conduction Study (NCS)
Electromyography (EMG) when required

Accurate diagnosis helps determine the severity and appropriate treatment.

Non-Surgical Treatment Options

Many patients improve with conservative treatment if diagnosed early.

Treat the Underlying Cause

Managing conditions such as:

Thyroid disorders
Diabetes
Obesity
Wrist swelling

can significantly reduce symptoms.

Wrist Splint

A wrist splint helps keep the wrist in a neutral position, especially during sleep, reducing pressure on the median nerve.

Medications

Doctors may prescribe medications to reduce:

Pain
Inflammation
Swelling

These should only be taken under medical supervision.

Physiotherapy

Hand and wrist exercises may help:

Improve nerve mobility
Reduce stiffness
Strengthen hand muscles
Improve wrist function

Activity Modification

Reducing repetitive wrist movements and taking regular breaks can help prevent worsening of symptoms.

When is Surgery Needed?

If symptoms persist despite conservative treatment or if nerve compression becomes severe, surgery may be recommended.

One commonly performed procedure is Micro Decompression of the Median Nerve.

During this procedure:

The tight ligament compressing the median nerve is carefully released.
Pressure on the nerve is relieved.
Symptoms such as numbness and tingling gradually improve.
The procedure is minimally invasive and is usually performed as a day-care surgery.

Early surgical treatment can prevent permanent nerve damage in advanced cases.

Tips to Prevent Carpal Tunnel Syndrome

You can reduce your risk by:

Maintaining a healthy weight
Managing thyroid disorders and diabetes
Taking frequent breaks while typing
Using proper wrist posture
Performing hand stretching exercises
Avoiding prolonged repetitive wrist movements
Using ergonomic keyboards and mouse devices
Treating wrist injuries promptly

When Should You Consult an Orthopedic Specialist?

Seek medical advice if you experience:

Persistent wrist pain
Finger numbness
Tingling that lasts for several days
Weakness while gripping objects
Frequent dropping of items
Night-time hand numbness
Symptoms that interfere with work or daily activities

Early diagnosis leads to better treatment outcomes.

Conclusion

Carpal Tunnel Syndrome is a common but treatable condition caused by compression of the median nerve at the wrist. Ignoring symptoms such as wrist pain, finger numbness, and tingling can lead to permanent nerve damage and reduced hand function.

With early diagnosis, treatment of underlying conditions, wrist support, physiotherapy, and, when necessary, micro decompression surgery, most patients can regain normal hand function and return to their daily activities comfortably.

If you are experiencing persistent wrist pain or numbness, consult an orthopedic specialist for a proper evaluation.
