What disease is the symptom of numbness in the middle finger?

Sometimes our fingers feel numb, especially the middle finger, which may be caused by cervical spondylosis. At this time, everyone needs to pay more attention to their cervical spine. However, other diseases can also cause numbness in the middle finger. So what disease is the numbness of the middle finger a precursor to?

1. Cervical spondylosis

Due to a series of pathological changes in cervical spondylosis, the spinal nerve roots may be compressed, stretched and irritated, causing numbness and swelling of the fingers. It manifests as numbness and swelling on the radial side or ulnar side, or on all five fingers, and may be accompanied by decreased grip strength. Cervical spondylotic radiculopathy can cause pain in the neck, back, head, upper limbs, and hands. The pain is usually dull, sore, burning, or a dull pain, or an electric shock-like pain. Numbness is often in the same area as pain, and the two often go together, but numbness often occurs in the fingers and forearms. The fingers and forearms have decreased sensation, and a few have areas of sensory hypersensitivity, which is often caused by irritation of the diseased segment.

2. Transient ischemic attack (TIA)

Elderly people who suffer from transient ischemic attack (TIA), also known as transient cerebral ischemia or "mini-stroke" often suffer from hypertension, hyperlipidemia and other symptoms. Hypertension can cause vascular spasms, high blood lipids can cause increased blood viscosity, and blood flow is relatively slow when sleeping at night. These factors can lead to transient cerebral ischemia and cause numbness of unilateral fingers. In particular, the initial symptoms of multiple cerebral infarctions are not obvious. Patients only feel numbness in their hands and feet, which does not affect their lives too much. If it is not discovered early, the best time for treatment will be delayed, causing limb movement disorders or even paralysis. Transient ischemic attack is a common and frequently occurring disease in neurology, accounting for approximately 7% to 45% of ischemic cerebrovascular diseases. 4% to 8% of patients suffer cerebral infarction within the first month after TIA.

3. Stroke

Stroke patients often experience symptoms such as headache, dizziness, limb numbness, and tongue swelling. Numbness and swelling in the fingers are one of the symptoms, but it is often accompanied by numbness in the arms and other parts of the body.

4. Diabetes

Diabetes can cause many complications. If peripheral neuropathy occurs, there will be symptoms such as numbness and abnormal sensation in the limbs.
