Introduction
Numbness in the tongue and fingers may be caused by peripheral neuritis, which typically results from lesions in the terminal fibers of sensory nerves. It could also be due to cervical spondylosis, such as herniated intervertebral discs or cervical bone spurs. The symptoms are usually transient. Additionally, numbness in the tongue and fingers can occur with cerebral infarction, typically resulting from involvement of the sensory center or sensory conduction pathways.

Tingling in the tongue and fingers may be caused by conditions such as peripheral neuritis, cervical spondylosis, or cerebral infarction.

1. Peripheral Neuritis

Tingling in the tongue and fingers may result from peripheral neuritis, which is usually due to lesions in the peripheral sensory nerve fibers. This condition may also be accompanied by numbness in the feet, reduced sensation in the hands and feet, or unsteady gait.

2. Cervical Spondylosis

The above symptoms could also be caused by cervical spondylosis, such as herniated discs or cervical bone spurs. The symptoms are typically transient. Patients may simultaneously experience limb weakness, difficulty walking, vomiting, or nausea. In severe cases, blurred vision and difficulty walking may occur.

3. Cerebral Infarction

Tingling in the tongue and fingers can also occur with cerebral infarction. This is usually due to involvement of the sensory center or sensory conduction pathways, leading to local or cerebral ischemia, thereby causing the aforementioned symptoms. Additional manifestations may include consciousness disturbances and motor dysfunction; severe cases may lead to paralysis.
