Carpal Tunnel Syndrome (CTS)

What is Carpal Tunnel Syndrome (CTS)?

Carpal tunnel syndrome (CTS) occurs when the median nerve, which runs through the carpal tunnel in the wrist, becomes compressed or irritated. This condition is often caused by repetitive motions, such as typing, playing musical instruments, or manual labor. It results in pain, numbness, tingling, and weakness in the hand and wrist, often affecting the thumb, index, and middle fingers.

Carpal tunnel syndrome is common among individuals who perform repetitive tasks that strain the wrist, and it can severely affect their ability to perform everyday activities.

Signs and Symptoms of Carpal Tunnel Syndrome

- Numbness or tingling in the thumb, index, and middle fingers

- Pain in the wrist, hand, or forearm

- Weakness or difficulty gripping objects

- "Pins and needles" sensation in the hand

- Symptoms that worsen at night or with repetitive use of the hand

Traditional Chinese Medicine (TCM) and Carpal Tunnel Syndrome

In TCM, carpal tunnel syndrome is viewed as an obstruction of Qi and blood flow in the meridians running through the wrist, particularly the pericardium and lung meridians. This obstruction can be caused by repetitive strain, overuse, or external pathogenic factors such as cold and dampness. TCM aims to promote the smooth flow of Qi and blood, reduce pain, and alleviate numbness.

TCM Diagnosis and Approaches:

- Qi and Blood Stagnation in the Meridians: Repetitive movements or strain can cause Qi and blood to become blocked in the wrist meridians, leading to pain and numbness.

- Herbs: Formulas like Shu Jing Huo Xue Tang (Relax the Channels and Invigorate the Blood Decoction) are often used to promote blood circulation and reduce pain. This formula includes herbs like Dang Gui (Angelica Sinensis), Tao Ren (Peach Kernel), and Hong Hua (Safflower).

- Cold-Damp Invasion: In some cases, exposure to cold and damp environments can cause Qi and blood to stagnate in the wrist, leading to stiffness and pain.

- Acupuncture: Acupuncture points like Pericardium 6 (Nei Guan), Lung 7 (Lie Que), and Large Intestine 4 (He Gu) can help alleviate pain, reduce inflammation, and restore normal function to the hand and wrist.

- Heat and Inflammation: In more severe cases, the obstruction of Qi and blood may cause heat, resulting in redness, swelling, and more intense pain.

- Moxibustion Therapy: Moxibustion is used to warm the wrist and promote the flow of Qi and blood, which can help relieve pain and numbness.

Lifestyle Recommendations

- Ergonomic Adjustments: Adjusting the workspace, such as using an ergonomic keyboard or wrist support, can help reduce strain on the wrist and prevent further injury.

- Dietary Therapy: Anti-inflammatory foods like ginger, turmeric, and omega-3-rich fish can help reduce inflammation and promote healing in the wrist.
