Carpal Tunnel Syndrome: Causes, Treatment, and Prevention

Carpal tunnel syndrome occurs when the median nerve in the hand is compressed, leading to weakness, numbness, or a tingling sensation. This nerve provides sensation to all the fingers, and the condition can affect one or both hands. Swelling inside the wrist can compress the median nerve, leading to numbness, tingling, or even paralysis on the thumb side of the hand.

In some people, it does get a lot worse with time and may even lead to dysfunction of the hand if left untreated. For this reason, it is imperative to diagnose and treat carpal tunnel syndrome at the earliest.

Symptoms

1. Numbness, tingling, and pain in your thumb.
2. There will be a burning sensation in your arm.
3. Nighttime wrist pain that disrupts sleep.
4. Weakness in the muscles of the hand

Causes

The pain in carpal tunnel syndrome is caused by pressure on the median nerve and inflammation in the wrist. This inflammation causes an underlying medical condition, causing swelling in the wrist. Some common conditions linked to carpal tunnel syndrome include

1. Diabetes
2. Thyroid dysfunction
3. Fluid retention from pregnancy or menopause
4. High blood pressure
5. Autoimmune disorders
6. Fractures to the wrist

When the wrist is repeatedly overextended, it can lead to the worsening of carpal tunnel syndrome. The repeated motion results in swelling and compression of the median nerve. This could be due to the following reasons:

1. Your wrist position when working on your keyboard or using your mouse.
2. Extended vibration exposure from utilising hand or power tools
3. Repeated wrist movements.

Risk Factors

Women are three times as likely as men to suffer from carpal tunnel syndrome. People between 30 and 60 are more susceptible to carpal tunnel syndrome. Diabetes, high blood pressure, and arthritis are all illnesses that increase your chances of having it.

Some lifestyle factors that influence the increase in carpal tunnel syndrome are

1. Smoking
2. High salt intake
3. Sedentary lifestyle
4. High BMI

People involved in jobs that involve the movement of their wrists are at a higher risk of developing carpal tunnel syndrome. Some jobs that require a lot of wrist movement are

1. Manufacturing
2. Assembly line work
3. Keyboarding occupations
4. Construction work

Diagnosis

Doctors can diagnose carpal tunnel syndrome based on your medical history, physical exam, and nerve conduction testing. A physical examination includes a full check-up of your hand, wrist, shoulder, and neck muscles for any other cause of nerve pressure. In addition, they will assess the sensitivity in your fingers as well as the strength of the muscles in your hand.

Treatment

The treatment solely depends on the severity of the symptoms and whether there is weakness in your hands. Some of the non-surgical methods are listed as follows:

1. Avoid positions that overextend your wrist.
2. Wrist splints hold the hand in a neutral position
3. Mild pain medication to reduce inflammation.
4. Treatment of any underlying conditions.

The surgical procedure entails severing the tissue band over the median nerve in the wrist to relieve nerve pressure.

Recovery

You will be asked by your doctor to move your hand above your heart and fingers to reduce swelling and stiffness right after the surgery. There will be swelling and stiffness after the surgery. The soreness in the palm may last from several weeks to months. Nighttime symptoms improve in some patients after the surgery.

Complications

Although complications are unavoidable in any surgery, doctors and surgeons will take every precaution to prevent those complications and dangers. A few complications of carpal tunnel syndrome are:

• Bleeding
• Infection
• Wound healing issues
• Nerve aggravation or injury

Outcomes

The surgery itself will improve the symptoms of carpal tunnel syndrome for most patients. However, recovery might be gradual, and it might take a year for a complete recovery. If you experience maximal discomfort in your hands for more than two weeks, your surgeon will refer you to a hand therapist who will assist you in speeding up your rehabilitation.

Prevention Techniques

1. Carpal tunnel syndrome can be prevented through changes in your lifestyle habits.
2. Managing underlying conditions like diabetes, hypertension, and arthritis promptly can lower the risk of developing carpal tunnel syndrome.
3. Pay close attention to the physical posture of your hand and avoid actions that cause your wrist to overextend.

Exercises

Regular hand and wrist exercises can help alleviate symptoms and improve mobility.

• Wrist Rotations: Move wrists in circular motions to enhance flexibility.
• Finger & Thumb Stretches: Spread fingers wide, then relax; gently pull the thumb back for a mild stretch.
• Prayer Stretch: Press palms together under the chin, then lower toward the waist for a deep stretch.
• Wrist Flexor & Extensor Stretch: Extend the arm, bend the wrist up (flexor) or down (extensor), and hold.
• Tendon Glides: Slowly curl fingers into a fist and extend back to improve movement.
• Hand Squeeze: Squeeze a soft ball or rolled-up socks to strengthen grip.
• Wrist Curls: Use light weights to strengthen forearm muscles.
• Shake It Out: Gently shake hands to relieve stiffness, especially at night.

Perform these exercises daily to reduce discomfort and maintain wrist health.
