What causes numbness in the right thumb?

Generally, numbness in the right thumb may be related to factors such as localized nerve damage, carpal tunnel syndrome, or cervical spondylosis. Patients can relieve symptoms through medications, physical therapy, and other treatments.

1. Localized nerve damage: If the patient has sustained trauma to the right thumb, it may result in nerve damage, causing numbness. Medications such as mecobalamin tablets or oryzanol tablets may be used under medical guidance to alleviate symptoms.

2. Carpal tunnel syndrome: Prolonged work at a computer may cause the wrist to continuously contact the desk or experience pressure, leading to carpal tunnel syndrome. This condition can cause symptoms such as numbness and weakness in the fingers. Treatment options like ultrasound therapy or low-level laser therapy at a hospital can help relieve these symptoms.

3. Cervical spondylosis: Trauma to the cervical spine or prolonged overstretching may trigger cervical spondylosis. When body position changes, nerves supplying the hand may become compressed, resulting in numbness in the right thumb. Treatments such as ultrashort wave therapy or interferential current therapy can help relieve this nerve compression.
