Carpal Tunnel Syndrome

Carpal Tunnel Syndrome is a common health issue that affects the hand and wrist. It is referred to as a “syndrome” because it involves a recognizable set of symptoms, such as pain, numbness, and weakness. While not life-threatening, it can impact a person’s ability to perform work tasks or enjoy everyday activities.

Causes of Carpal Tunnel Syndrome

Because the carpal tunnel is a tight space, any swelling or inflammation can compress the median nerve, triggering the syndrome. Several factors can lead to this nerve compression, including:

• Repetitive hand movements, which may thicken or irritate tendons.
• Medical issues that cause swelling in the wrist.
• Circulation problems.
• Certain medications that cause fluid buildup.
• Injuries to the wrist.
• Hormonal changes during pregnancy or menopause.
• Obesity.

People who frequently type, use vibrating tools, or perform repetitive tasks with their hands—especially if the hand is lower than the wrist—are more likely to develop this condition.

Medical conditions like diabetes, rheumatoid arthritis, and hypothyroidism can also contribute. In rare cases, a cyst or tumor inside the tunnel may compress the nerve.

Symptoms to Watch For

Carpal tunnel syndrome symptoms typically begin slowly and may include:

• Tingling or burning in the palm.
• Numbness or itching in the hand, often without visible swelling.
• A feeling that fingers are swollen or hard to move.
• Weak grip strength.
• Reduced sensitivity to temperature changes.
• Pain in the wrist or hand that may radiate up the arm.
• Discomfort or aching in the wrist area.
• Muscle weakening at the base of the thumb, especially in long-term cases.

Some people first notice symptoms at night, waking up with tingling or numb hands due to bending the wrists while sleeping. Symptoms often vary by individual and tend to get worse over time if not addressed.

Diagnosis Process

Early diagnosis is important to prevent long-term nerve damage. Doctors usually take several steps to identify the condition:

• Reviewing the patient’s medical history to check for repetitive hand use or underlying conditions.
• Physical examination of the hand, wrist, arm, neck, and shoulder to detect swelling, weakness, or muscle loss.
• X-rays to rule out arthritis or fractures.
• Blood tests to identify other conditions like diabetes.
• Manual and diagnostic tests, such as:
   Tinel’s sign – tapping the median nerve to check for tingling.

• Phalen’s test – bending the wrist to see if it triggers symptoms.

• Nerve conduction studies and EMG – measuring nerve function and muscle  activity.
• Ultrasound – to detect nerve swelling.
• MRI scans – for a detailed view of wrist anatomy.

Treatment Options

When caught early, carpal tunnel syndrome often responds well to non-surgical treatments. The goal is to relieve pressure on the median nerve and prevent further damage.

Non-surgical treatments may include:

• Wearing a wrist splint, especially at night, to keep the wrist straight.
• Injecting corticosteroids to reduce inflammation and pain.
• Taking NSAIDs (like ibuprofen) to relieve swelling.
• Treating underlying health issues such as arthritis or thyroid problems.
• Doing wrist and hand exercises at home to stretch tight tissues and improve flexibility.

These exercises might involve finger stretches, wrist bends, and nerve gliding techniques. They can help reduce symptoms and prevent the condition from worsening.

Surgical Treatments

If symptoms persist or worsen, surgery may be necessary. Two main surgical options are available:

Endoscopic surgery – involves small incisions and a camera to guide the cutting of the carpal ligament.

Open-release surgery – a more traditional approach, involving a single larger incision to cut the ligament and relieve pressure.

Recovery Outlook

Most people recover well from treatment, and surgery often leads to full recovery, assuming no other conditions are complicating the issue. While healing may take time, especially after surgery, the syndrome rarely comes back.

Other Possible Treatments

Epidural injections in some cases.

Specialist consultations for diagnosis and treatment planning.
