Finger Numbness: Causes and When to Seek Help

Numbness in the fingers?

Hello, doctor.
A few days ago, I felt numbness in my hand, and it felt like I was being electrocuted.
Now, only my fingertips are numb.
I went to see a neurologist, and after a preliminary examination, he asked if I felt an electric shock sensation.
I said yes, and he immediately recommended an MRI and advised me to schedule it as soon as possible.
After the examination, he suggested I make an outpatient appointment, and if I can't get an appointment, he told me to go directly to the outpatient clinic to see him.
Is this a serious condition?

Dear Mr.
Jayen,
You mentioned "finger numbness...
MRI examination," which clinically may suggest cervical nerve compression.
Typical discomfort symptoms associated with cervical radiculopathy include pain in the shoulder or arm, as well as numbness, tingling, and weakness in the palm and fingers.
Cervical joint disorders can lead to neck pain and stiffness, causing pain due to compression of nearby nerve roots, which may even radiate to the temporal region of the head, shoulder, arm, and hand, resulting in discomfort.
Magnetic resonance imaging (MRI) can provide insights into the structure of related tissues and help rule out lesions that may require surgical intervention.

It is generally recommended to combine this with nerve conduction studies to assess the conduction velocity and waveform of large fiber nerves.
Electromyography (EMG) can evaluate muscle responses in the areas supplied by the affected nerves.

In terms of clinical treatment:
1.
Medication: When nerves are compressed, an inflammatory response occurs, leading to symptoms such as pain, numbness, and weakness.
Non-steroidal anti-inflammatory drugs (NSAIDs) are recommended as they possess both anti-inflammatory and analgesic properties, which can reduce inflammation and alleviate pain.
2.
Cervical collar stabilization: This helps prevent cervical instability and avoids further damage to neural tissues, particularly in cases of trauma such as sports injuries, car accidents, or falls that result in excessive flexion or extension of the cervical spine.
I recommend that you consult with a neurologist or a rehabilitation specialist to discuss further examination and treatment options.
Thank you for your inquiry, and feel free to reach out with any related questions!
Wishing you good health and peace,
Dr.

More Info

Finger numbness can be a concerning symptom, and it’s understandable that you’re feeling anxious about it. Numbness, especially when accompanied by sensations like tingling or electric shocks, can indicate various underlying issues, some of which may require prompt medical attention.
The sensation of numbness in your fingers can arise from several causes. One common reason is nerve compression or irritation, which can occur due to conditions such as carpal tunnel syndrome, where the median nerve is compressed at the wrist. This often leads to numbness, tingling, and weakness in the hand, particularly affecting the thumb, index, and middle fingers. Another possibility is cervical radiculopathy, where nerve roots in the neck are compressed, leading to symptoms that radiate down the arm into the fingers.

Other potential causes of finger numbness include peripheral neuropathy, which can result from diabetes, vitamin deficiencies, or alcohol use. In some cases, systemic conditions such as multiple sclerosis or rheumatoid arthritis can also present with numbness and tingling in the extremities.
Given that your neurologist has recommended an MRI, it suggests that they are looking for structural issues that could be affecting your nerves, such as herniated discs or other abnormalities in the cervical spine. The urgency in scheduling the MRI and follow-up appointments indicates that your doctor is taking your symptoms seriously, which is important for ensuring that any serious conditions are ruled out or addressed promptly.

It’s essential to follow through with the recommended MRI and any subsequent evaluations. Early diagnosis can lead to more effective treatment options and potentially prevent the progression of any underlying conditions. If the MRI reveals significant findings, your doctor may discuss treatment options that could include physical therapy, medications, or possibly surgical interventions, depending on the severity and nature of the issue.

In the meantime, there are some general measures you can take to help alleviate symptoms. Ensure that you maintain good posture, especially if you spend long hours at a computer. Taking regular breaks to stretch and move your hands and arms can also help reduce nerve compression. If you notice that certain positions exacerbate your symptoms, try to avoid them.

If you experience any worsening of your symptoms, such as increased weakness, loss of coordination, or changes in bowel or bladder function, it’s crucial to seek immediate medical attention. These could be signs of a more serious condition that requires urgent care.

In summary, while finger numbness can stem from various causes, the recommendation for an MRI indicates that your neurologist is being thorough in their evaluation. It’s important to follow their advice and keep an open line of communication regarding any changes in your symptoms. Taking proactive steps now can lead to better outcomes in the long run.
