What causes numbness in the palms and fingers?

Normally, numbness in the palms and fingers may be caused by maintaining the same posture for a prolonged period, localized pressure, multiple peripheral neuritis, cervical spondylosis, diabetes, etc. It is recommended to seek timely medical examination to identify the underlying cause and receive standardized treatment under the guidance of a qualified physician. Details are as follows:

1. Prolonged Maintenance of the Same Posture

Maintaining the same posture for an extended period, such as using a computer or mobile phone for long durations or prolonged desk work, may lead to poor local blood circulation, thereby causing numbness in the palms and fingers. Symptoms can be relieved through appropriate physical activity and adequate rest.

2. Localized Pressure

Prolonged gripping of heavy objects or pressure on the arms during sleep may lead to restricted local blood circulation and impaired nerve conduction, potentially causing numbness in the palms and fingers. Symptoms can be alleviated by relieving the pressure and moving the fingers.

3. Multiple Peripheral Neuritis

The causes of multiple peripheral neuritis may include poisoning, nutritional and metabolic disorders, infections, immune-mediated conditions, etc. Inflammation may damage the peripheral nerves and disrupt nerve conduction, leading to symptoms such as numbness in the palms and fingers. It may be accompanied by loss of sensation, pain, and muscle weakness. Treatment may include medications such as vitamin B12 tablets, vitamin B1 tablets, and methylcobalamin tablets, as directed by a physician to alleviate symptoms.

4. Cervical Spondylosis

Cervical spondylosis is a condition caused by degenerative changes in the cervical intervertebral discs, cervical bone spurs, and other factors. Lesions in the cervical spine may compress nerve roots, causing numbness, pain, and other symptoms in the palms and fingers. It may also be accompanied by neck pain, stiffness, and dizziness. Treatment may include medications such as chlorzoxazone tablets, eperisone hydrochloride tablets, and naproxen sodium tablets, as directed by a physician.

5. Diabetes

Diabetes is a metabolic disorder caused by insufficient insulin secretion or impaired insulin function, leading to elevated blood glucose levels. Prolonged high blood sugar levels may lead to multiple peripheral neuritis, causing symptoms such as numbness in the palms and fingers. It may also be accompanied by increased thirst, frequent urination, and weight loss. Treatment may include medications such as insulin degludec injection, orlistat capsules, and acarbose capsules, as directed by a physician.

In daily life, maintain a balanced diet, control blood sugar levels, and avoid excessive intake of sugary and greasy foods. Additionally, engage in regular physical exercise to improve physical fitness and enhance immunity.
