Why does my right middle finger hurt?

If we use our hands excessively, it will cause temporary pain in our fingers, which will recover after a short rest. But sometimes it still hurts after resting, then this may be caused by an illness. So why does the middle finger of my right hand feel painful?

The sensory nerves of the fingers are derived from the nerve roots of the cervical spinal cord, forming the brachial plexus in the cervical axilla, and then dividing into the radial nerve, median nerve, ulnar nerve, etc., passing through the upper arm and forearm, becoming peripheral nerves and distributed to the hands and fingers. When the nerves in these areas are damaged, inflamed, have tumors, are compressed, etc., causing abnormal sensation, numbness and pain in the fingers will occur.

Common diseases that cause numbness and pain in fingers include:

1. 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. It can usually be recovered after the cause is eliminated. Treatments such as oral or injection of vitamin B1, acupuncture, etc. can promote recovery.

2. 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 impaired movement of some fingers. The ulnar nerve groove behind 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.

3. 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 susceptible to injury or pressure, which is called carpal tunnel syndrome. The treatment principles are the same as before.

4. 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.

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

6. Cervical spondylosis can cause unilateral or bilateral finger numbness and pain due to compression of cervical nerve roots or cervical spinal cord by cervical vertebrae hypertrophy or cervical disc degeneration and protrusion, and gradually develop to the upper arm, forearm, and even upper limb movement disorders.
