Wrist pain and numbness?


Hello Doctor, I have recently been experiencing weakness in my left pinky finger, and it feels sore when I try to exert force.
Sometimes, when I'm typing, I also feel a tingling sensation.
Additionally, the flexibility of my pinky has significantly decreased compared to before, and after massaging it, the soreness returns.
What treatment and rehabilitation options do you recommend?

Hello! I personally believe that 1.
tendon strain, 2.
bone issues, 3.
uric acid problems, and 4.
poor posture should be considered in order of exclusion.
Thank you for your inquiry!

More Info


Wrist pain and numbness, particularly in the context of your left pinky finger, can be indicative of several underlying conditions. Based on your description, it seems like you might be experiencing symptoms related to nerve compression or irritation, possibly due to conditions such as ulnar nerve entrapment, also known as cubital tunnel syndrome. This condition occurs when the ulnar nerve, which runs along the inner side of the elbow and down to the hand, becomes compressed or irritated, leading to symptoms like pain, numbness, and weakness in the pinky and ring fingers.


Possible Causes
1. Ulnar Nerve Entrapment: As mentioned, this is a common cause of numbness and weakness in the pinky finger. It can occur due to prolonged pressure on the elbow, repetitive motions, or direct trauma.

2. Carpal Tunnel Syndrome: Although this condition primarily affects the thumb, index, middle, and part of the ring finger, it can sometimes cause symptoms that radiate to the pinky finger, especially if there is a coexisting condition affecting the ulnar nerve.

3. Tendonitis or Tenosynovitis: Inflammation of the tendons in the wrist can lead to pain and discomfort, which may also affect the function of the fingers.

4. Cervical Radiculopathy: Nerve root compression in the neck can lead to symptoms in the arm and hand, including the pinky finger.

5. Repetitive Strain Injury: Activities that involve repetitive wrist and hand movements can lead to strain and discomfort, potentially affecting nerve function.


Treatment Options
1. Rest and Activity Modification: Avoid activities that exacerbate your symptoms. If you find that certain movements or positions worsen the pain or numbness, try to modify or limit those activities.

2. Ergonomic Adjustments: If your symptoms are related to your work, consider adjusting your workstation. Ensure that your wrist is in a neutral position while typing or using a mouse. Wrist supports or ergonomic keyboards may also help.

3. Physical Therapy: A physical therapist can provide exercises to strengthen the muscles around the wrist and improve flexibility. They can also teach you techniques to alleviate pressure on the ulnar nerve.

4. Splinting: Wearing a wrist splint, especially at night, can help keep your wrist in a neutral position and reduce pressure on the nerves.

5. Medications: Over-the-counter anti-inflammatory medications, such as ibuprofen or naproxen, can help reduce pain and inflammation. If your symptoms are severe, a doctor may prescribe stronger medications.

6. Corticosteroid Injections: In some cases, corticosteroid injections can help reduce inflammation around the nerve.

7. Surgery: If conservative treatments do not provide relief and your symptoms persist, surgical options may be considered to relieve pressure on the nerve.


Rehabilitation
Rehabilitation exercises can be beneficial in restoring strength and function to your wrist and fingers. Here are a few exercises you might consider:
- Wrist Flexor Stretch: Extend your arm in front of you with your palm facing up. Use your other hand to gently pull back on your fingers to stretch the wrist flexors.

- Wrist Extensor Stretch: Extend your arm with your palm facing down. Use your other hand to gently pull back on your fingers to stretch the wrist extensors.

- Nerve Gliding Exercises: These exercises can help the ulnar nerve move more freely through the cubital tunnel.

- Strengthening Exercises: Once the pain subsides, gradually introduce strengthening exercises for the wrist and hand.


Conclusion
It’s essential to consult with a healthcare professional, such as a neurologist or an orthopedic specialist, to obtain a proper diagnosis and treatment plan tailored to your specific situation. They may recommend imaging studies, such as an MRI or nerve conduction studies, to assess the condition of your nerves and surrounding structures. Early intervention can help prevent further complications and improve your overall function.
