Hand Numbness and Arm Pain: When to See a Neurologist

Numbness in the hands and arm pain?

I'm not sure if it's due to nerve compression in the wrist from exercising or prolonged computer use, but my fingers are numb, and my wrist cannot extend back to 90 degrees like it used to.
I visited a clinic where I was prescribed anti-inflammatory medication (which I stopped taking due to increased heart rate) and vitamin B12.
It's been a week, and while there has been some improvement, certain positions still cause numbness.
Should I see a neurologist?

Dear Mr.
August,
You mentioned that "after prolonged computer use, my fingers feel numb," which may indicate common median nerve injury or ulnar nerve injury.
Median nerve injury, also known as carpal tunnel syndrome, typically occurs in individuals who perform repetitive wrist movements, such as mechanics, carpenters, and typists, particularly affecting the dominant hand, with symptoms exacerbated by work activities.

To diagnose carpal tunnel syndrome or ulnar nerve injury, clinical neurological examination is essential, and nerve conduction studies can also be utilized.
Nerve conduction studies involve the application of very small electrical currents to stimulate the nerves, allowing assessment of nerve response and the extent of injury.
For maintaining peripheral nerve health, it is advisable to avoid excessive use of hand muscles, take breaks and perform stretching exercises every half hour, and increase the intake of antioxidant-rich foods, including vegetables and fruits, as well as B-complex vitamins.

I recommend consulting with a neurologist or a rehabilitation specialist for further evaluation and discussion.
Thank you for your inquiry, and feel free to reach out for further discussion.
Wishing you good health, peace, and joy.
Dr.
Jiang Junyi, Tao Medical Center, cares about you.

More Info

When experiencing hand numbness and arm pain, particularly if these symptoms persist or worsen, it is crucial to seek medical advice from a neurologist. Your symptoms, which include numbness in the fingers and difficulty with wrist movement, could indicate a variety of underlying issues that may require specialized evaluation and treatment.

Firstly, it is essential to consider the potential causes of your symptoms. Numbness in the fingers and pain in the arm can often be attributed to nerve compression or irritation. This can occur due to repetitive strain injuries, such as those caused by prolonged computer use or improper wrist positioning while typing. Conditions like carpal tunnel syndrome, where the median nerve is compressed at the wrist, are common in individuals who spend significant time on computers. Symptoms typically include numbness, tingling, and weakness in the hand, particularly in the thumb, index, and middle fingers.

Another possibility is cervical radiculopathy, which occurs when a nerve in the neck is compressed or irritated, leading to pain, numbness, or weakness that radiates down the arm. This can happen due to herniated discs, degenerative disc disease, or other spinal issues. If your symptoms are accompanied by neck pain or if you have a history of neck injuries, this could be a significant factor.

You mentioned that you have taken anti-inflammatory medication and vitamin B12 supplements. While B12 deficiency can lead to neurological symptoms, including numbness and tingling, it is essential to ensure that your levels are adequate and that there are no other underlying deficiencies or metabolic issues. If you have not already done so, a blood test to check for vitamin levels, thyroid function, and other relevant markers may be beneficial.

Given that your symptoms have shown some improvement but still persist with certain positions, it is advisable to consult a neurologist. A neurologist can perform a thorough examination, which may include a detailed history, physical examination, and possibly nerve conduction studies or electromyography (EMG) to assess the function of your nerves and muscles. These tests can help determine if there is any nerve damage or dysfunction and guide appropriate treatment options.

In the meantime, consider implementing ergonomic adjustments to your workspace. Ensure that your wrists are in a neutral position while typing, and take regular breaks to stretch and move your hands and arms. Wrist splints, especially at night, can also help alleviate symptoms by keeping the wrist in a neutral position and reducing pressure on the nerves.

In summary, while some improvement has been noted, the persistence of your symptoms warrants further evaluation by a neurologist. Early intervention can prevent potential complications and improve your quality of life. Don't hesitate to seek help; your health and comfort are paramount.
