Finger Pain and Numbness from Gaming: Causes and Solutions

Long-term use of the index finger on the keyboard can lead to pain in the finger joints and numbness in the index finger when holding objects while standing?

Due to playing some online games, I may have caused pain in the joint of my index finger from excessive clicking.
Now, whenever I stand, grip something, or perform certain actions, this finger feels numb.
However, if I don't touch it, the numbness isn't noticeable; it only becomes apparent when I touch it or when it comes into contact with something, and it can last for a long time, from half a day to a full day.
To put it simply, this sensation is different from the typical numbness one feels in their hand, which usually resolves by shaking it.
In my case, I don't feel the numbness when the finger is still; instead, it intensifies with movement.
When I touch the index finger, I can distinctly feel the numbness.
Initially, the numbness was only at the fingertip, but now it has progressed to the second joint.
At first, the numbness lasted only a few minutes, but now it can persist for a long time.
Externally, there are no visible signs of swelling or significant changes.
The pain in my index finger began two years ago, and after I stopped playing that game, it improved significantly.
However, now that I've returned to playing, the symptoms have reappeared, and the finger numbness only started occurring this year.
Could you please advise what might be causing this issue?

Hello, based on your description, your symptoms seem to resemble sensory abnormalities in the distribution areas of the sixth and seventh cervical nerve roots caused by nerve compression.
Shoulder, neck, and back pain are common ailments in modern individuals, especially among those who work long hours sitting in office chairs or white-collar workers.
The causes are often due to overwork or poor posture, leading to inflammation of the shoulder and back muscles or cervical nerve root compression.

The main contributing factors are occupational risk factors, such as maintaining the same posture for extended periods, particularly poor postures, which typically involve neck flexion exceeding 20 degrees, extension beyond 5 degrees, or twisting positions.
Additionally, improper exertion, repetitive neck movements, prolonged shoulder elevation, and extended screen or microscope use are significant contributors.
To treat cervical nerve root compression, it is essential to target the specific area of the nerve root for effective results.
If symptoms such as difficulty urinating, constipation, or urinary incontinence occur, it indicates that cervical spine degeneration has become quite severe.
At this point, it is advisable to seek further imaging studies and surgical treatment at a medical facility to prevent serious spinal or nerve damage.

It is recommended to consult with a neurologist or a rehabilitation physician for examination and discussion.
Wishing you good health and peace.

More Info

The symptoms you are experiencing with your index finger, including pain and numbness, are likely related to repetitive strain injuries, which are common among individuals who engage in prolonged activities that require repetitive motions, such as gaming. The specific sensations you describe—numbness that only occurs when the finger is touched or when it is engaged in certain activities—suggest that there may be some form of nerve compression or irritation at play.

Possible Causes
1. Nerve Compression: The symptoms you describe could be indicative of nerve compression, possibly involving the median nerve or the ulnar nerve. This can occur due to repetitive movements or sustained pressure on the nerves, which can happen when gripping a controller or keyboard for extended periods.

2. Tendonitis: Overuse of the finger can lead to inflammation of the tendons, known as tendonitis. This condition can cause pain and discomfort, especially when moving the affected finger or when pressure is applied.

3. Trigger Finger: The sensation of your finger getting stuck or feeling stiff could also be a sign of trigger finger (stenosing tenosynovitis), where the tendons that control finger movement become inflamed and cause the finger to lock or catch.

4. Cervical Radiculopathy: Given that you mentioned the numbness can extend from the fingertip to the second joint, it is also worth considering cervical radiculopathy, where nerve roots in the neck are compressed, leading to symptoms in the arm and hand.

5. Poor Ergonomics: The position in which you hold your gaming device or keyboard can contribute to these symptoms. Poor ergonomics can lead to strain on the muscles and nerves in the hand and wrist.

Treatment Options
1. Rest and Modification of Activities: The first step in treatment is to reduce or modify the activities that exacerbate your symptoms. Taking breaks during gaming sessions and avoiding prolonged gripping can help alleviate symptoms.

2. Ergonomic Adjustments: Ensure that your gaming setup is ergonomically sound. This includes using a chair that supports your back, keeping your wrists in a neutral position, and using devices that minimize strain on your fingers.

3. Physical Therapy: Engaging in physical therapy can help strengthen the muscles around the affected area and improve flexibility. A therapist can provide exercises tailored to your specific needs.

4. Ice and Anti-Inflammatory Medications: Applying ice to the affected area can reduce inflammation and pain. Over-the-counter anti-inflammatory medications, such as ibuprofen, can also be beneficial.

5. Splinting: In some cases, using a splint to immobilize the finger or wrist can help reduce strain and allow for healing.

6. Medical Evaluation: If symptoms persist or worsen, it is advisable to seek a medical evaluation. A healthcare professional may recommend imaging studies or nerve conduction studies to assess for any underlying conditions.

7. Corticosteroid Injections: For persistent symptoms, corticosteroid injections may be considered to reduce inflammation around the affected nerves or tendons.

8. Surgery: In severe cases, surgical intervention may be necessary to relieve nerve compression or to address tendon issues.

Conclusion
In summary, the symptoms you are experiencing with your index finger are likely related to repetitive strain from gaming. It is essential to address these symptoms early to prevent further complications. Implementing ergonomic adjustments, taking breaks, and possibly seeking physical therapy can significantly improve your condition. If symptoms persist, consulting with a healthcare professional is crucial for a comprehensive evaluation and tailored treatment plan.
