Why do my fingertips go numb

My fingers are a part of my body that I use most frequently. Because of this, sometimes they may experience abnormal conditions, such as numbness. Numbness in the limbs often occurs when the limbs are under pressure. If our fingers are often numb, we should pay attention to it. It may be caused by disease. There are many related types of diseases. So, why do your fingertips feel numb? Let’s find out the specific reasons below.

Peripheral neuritis

The peripheral nerves of the fingers may cause inflammatory reactions due to poisoning, infection, vitamin B deficiency, blood supply disorders in the fingers, etc., which may cause numbness and pain in the fingers. Most of the time, it occurs at the same time on the fingers of both hands, and the disease can usually be recovered after the cause is eliminated. Treatments such as oral or injection of vitamin B1, acupuncture, etc. can promote recovery.

Ulnar nerve damage

When the ulnar nerve in the forearm and upper arm is injured, compressed, or develops a tumor, it can cause numbness and pain in the little finger and ring finger on the same side and partial finger movement disorders. The ulnar nerve groove at the back of the elbow is more susceptible to injury or compression. Most cases will gradually recover in about half a year after the injury, but if there is a tumor, complete rupture or severe pressure, surgical treatment is often required.

Median nerve damage

The median nerve in the forearm and upper arm may cause numbness and pain in the palm, thumb, index finger, and middle finger due to trauma, tumor, compression, etc. The wrist is most vulnerable to injury or pressure, which is called carpal tunnel syndrome. The treatment principles are the same as before.

Radial nerve damage

The radial nerve is more susceptible to damage in the middle and lower outer parts of the upper arm, resulting in numbness and pain on the back of the thumb and index finger and drooping of the fingers and wrist. The treatment principles are the same as before.

Brachial plexus damage

Lesions or injuries in the axilla or anterior neck may cause mixed symptoms of complete or partial damage to the ulnar, median, and radial nerves. The treatment principles are the same as before.

Cervical Spondylosis

Due to compression of the cervical nerve roots or cervical spinal cord by cervical vertebrae hypertrophy or cervical disc degeneration and protrusion, numbness and pain in unilateral or bilateral fingers may occur, especially in the right fingers. Sometimes the entire arm to the shoulder may be numb and painful, making it difficult to hold a pen or knit a sweater. This is consistent with the condition of cervical spondylosis. The letter says that when the hands are hanging down without exerting force, there will be no numbness or pain in the hands. It means that the right upper limb is not compressed after relaxation and the lesion is relatively mild.
