Dr. Chen Shunsheng reply Rare Disease

Peripheral nerve-related conditions include the following possibilities, arranged by frequency of occurrence:
1.
Carpal Tunnel Syndrome: This condition occurs when the median nerve is compressed as it passes through the carpal tunnel at the wrist.
It is commonly seen in individuals whose occupations or sports involve repetitive wrist movements.
Symptoms include numbness in the first to fourth fingers (half of the fourth finger) and the palm, which worsens when gripping objects.
Tapping over the carpal tunnel or flexing the hand may provoke the numbness.
In severe cases, atrophy of the thenar muscles may occur.
It can affect one or both hands.
2.
Ulnar Nerve Entrapment: This is most commonly caused by compression of the ulnar nerve as it passes through the cubital tunnel at the elbow, which can result from occupation, posture, or trauma.
Symptoms include numbness in the fourth (half) and fifth fingers.
Tapping over the cubital tunnel may elicit numbness.
In severe cases, atrophy of the hypothenar muscles and the interossei, as well as some forearm muscles, may occur.
It can affect one or both sides simultaneously.
3.
Cervical Radiculopathy: This condition is caused by compression of the cervical nerve roots due to cervical spine degeneration or intervertebral disc herniation.
Symptoms include: C6 radiculopathy: numbness and pain in the first to third fingers; C7 radiculopathy: numbness and pain in the third and fourth fingers; C8 and T1 radiculopathy: numbness and pain in the fourth and fifth fingers and the inner side of the arm.
Corresponding muscle groups may also experience weakness and atrophy.
As for what you need to do:
A.
Please consult a neurologist for a clinical neurological examination and diagnosis.
B.
Undergo nerve conduction studies and electromyography to confirm the clinical diagnosis.
C.
If cervical radiculopathy is suspected, further imaging studies such as cervical X-rays may be necessary.
D.
Treatment will depend on the diagnosis.
Wishing you a speedy recovery!

More Info

Long-term hand numbness can be a concerning symptom, especially when it occurs suddenly and frequently. Based on your description, it seems that you are experiencing numbness in your hands, particularly while riding a motorcycle, along with persistent mid-back pain. Given your profession in the restaurant industry, it is essential to consider various factors that could contribute to these symptoms.

Possible Causes of Hand Numbness
1. Nerve Compression: One of the most common causes of hand numbness is nerve compression. This can occur due to repetitive motions, poor posture, or prolonged pressure on certain areas of the body. For instance, if you are frequently lifting heavy objects or maintaining awkward positions while working in the restaurant, it could lead to conditions like carpal tunnel syndrome or thoracic outlet syndrome, where nerves in the arm and hand become compressed.

2. Cervical Spine Issues: Problems in the cervical spine (neck area) can also lead to numbness in the hands. Conditions such as herniated discs or cervical spondylosis can compress nerves that travel down the arms, resulting in numbness or tingling sensations.

3. Poor Circulation: Sometimes, numbness can be related to circulation issues. If blood flow to the hands is restricted, it can cause temporary numbness. This could be exacerbated by certain positions while riding a motorcycle or working in a restaurant.

4. Repetitive Strain Injury (RSI): Given your profession, repetitive strain injuries are a significant risk. These injuries occur from repetitive motions and can lead to inflammation and nerve irritation, resulting in numbness.

5. Systemic Conditions: Conditions such as diabetes, multiple sclerosis, or vitamin deficiencies (like B12 deficiency) can also cause numbness in the hands. If you have other symptoms or a family history of these conditions, it may be worth discussing with a healthcare provider.

Addressing Your Symptoms
1. Consult a Healthcare Provider: It is advisable to consult a healthcare provider, preferably a neurologist or an orthopedic specialist, who can evaluate your symptoms thoroughly. They may perform a physical examination, review your medical history, and possibly recommend imaging studies like X-rays or MRIs to identify any underlying issues.

2. Physical Therapy: Engaging in physical therapy can be beneficial. A physical therapist can help you with exercises to strengthen the muscles around your neck and shoulders, improve posture, and alleviate nerve compression.

3. Ergonomic Adjustments: Since you work in the restaurant industry, consider making ergonomic adjustments to your workspace. This could include using tools that reduce strain on your hands and wrists, as well as ensuring that your workstation is set up to promote good posture.

4. Regular Breaks: If your job involves repetitive motions, ensure you take regular breaks to stretch and rest your hands and arms. This can help prevent the onset of numbness and reduce strain on your muscles and nerves.

5. Lifestyle Modifications: Pay attention to your posture while riding your motorcycle and during work. Maintaining a neutral spine and avoiding positions that put pressure on your arms can help reduce symptoms.

6. Medication: If inflammation or pain is significant, over-the-counter anti-inflammatory medications may provide relief. However, consult with a healthcare provider before starting any medication.

Conclusion
In summary, long-term hand numbness can stem from various causes, including nerve compression, cervical spine issues, and repetitive strain injuries. Given your symptoms and profession, it is crucial to seek a professional evaluation to determine the underlying cause and appropriate treatment. Making ergonomic adjustments, engaging in physical therapy, and taking regular breaks can significantly help manage and alleviate your symptoms. If you suspect systemic conditions, discussing these with a healthcare provider is essential for proper diagnosis and management.
