Numbness in the abdominal area?


Hello, doctor.
This has never happened before, but recently it has occurred twice.
In the left side of my abdomen, a relatively small area suddenly feels very numb, almost like there is a thick layer of skin over it.
There is no pain or tingling sensation, just a feeling of reduced sensation—not completely numb, but as if there is an additional layer of skin.
The numbness quickly dissipates, but the sensation of that extra layer lingers a bit.
After some time or upon waking up, it returns to normal.
I would like to know what this situation might be.
Is treatment necessary?

Hello Mr.
Zheng: You mentioned that "the area on the left side of the abdomen is not large, but suddenly there is a lot of numbness, feeling like there is a thick layer of skin on top." This symptom may suggest a possible compression of the lumbar nerves due to peripheral nerve abnormalities.
Symptoms of peripheral nerve compression include: 1.
Pain characterized by burning or electric shock sensations.
2.
Symptoms have a specific dermatomal distribution, and touching or pressing can provoke the symptoms.
3.
Accompanied by muscle soreness and weakness.

Examinations for peripheral nerve issues can typically utilize electrophysiological tests to assist in diagnosis.
Nerve conduction studies: assess the conduction velocity and waveform of large fiber nerves.
Electromyography (EMG): evaluates muscle responses in the areas supplied by the affected nerves.

I recommend that you visit a neurology outpatient clinic for further examination and follow-up.
Thank you for your inquiry, and feel free to discuss any related questions! Wishing you good health and peace.
Dr.
Jiang Junyi, Taoyuan Hospital, cares about you.

More Info


Abdominal numbness, especially when it occurs suddenly and without accompanying pain, can be concerning and warrants careful consideration. The sensation you describe—similar to having a thick layer of skin over the affected area—could be indicative of several underlying issues. While the numbness itself may not be painful, it is essential to understand the potential causes and when to seek medical help.


Possible Causes of Abdominal Numbness
1. Nerve Compression or Irritation: One of the most common causes of numbness in any part of the body, including the abdomen, is nerve compression. This can occur due to various reasons, such as herniated discs in the spine, which may affect the nerves that innervate the abdominal area. If you have a history of back issues, this could be a contributing factor.

2. Peripheral Neuropathy: Conditions that affect the peripheral nerves, such as diabetes, vitamin deficiencies (especially B vitamins), or alcohol use, can lead to numbness or tingling sensations. If you have any risk factors for these conditions, it might be worth discussing with your healthcare provider.

3. Circulatory Issues: Reduced blood flow to the abdominal area can also cause numbness. This could be due to vascular issues or even temporary positions that compress blood vessels.
4. Muscle Strain or Spasm: Sometimes, muscle strain or spasms can lead to sensations of numbness or tingling. If you've engaged in physical activities that may have strained your abdominal muscles, this could be a possibility.

5. Gastrointestinal Issues: Certain gastrointestinal conditions, such as irritable bowel syndrome (IBS) or inflammatory bowel disease (IBD), can sometimes present with unusual sensations in the abdomen, including numbness.

6. Psychological Factors: Anxiety and stress can manifest physically in various ways, including numbness or tingling sensations. If you have a history of anxiety, this could be a contributing factor.


When to Seek Medical Help
While occasional numbness may not be a cause for alarm, there are specific situations where you should seek medical attention:
- Persistent Symptoms: If the numbness continues to occur frequently or lasts for an extended period, it is essential to consult a healthcare provider.


- Accompanied Symptoms: If you experience additional symptoms such as pain, weakness, changes in bowel or bladder function, or any signs of systemic illness (like fever or weight loss), you should seek medical attention promptly.

- Changes in Sensation: If the numbness progresses or changes in nature, such as becoming painful or spreading to other areas, it is crucial to get evaluated.

- Underlying Health Conditions: If you have existing health conditions that could complicate your symptoms (like diabetes or a history of neurological issues), it is advisable to consult your healthcare provider sooner rather than later.


Conclusion
In summary, while the occasional sensation of numbness in the abdomen may not be alarming, it is essential to monitor the frequency and nature of these episodes. If they persist or are accompanied by other concerning symptoms, seeking medical evaluation is crucial. A healthcare provider can perform a thorough assessment, which may include a physical examination, imaging studies, or nerve conduction tests, to determine the underlying cause and appropriate treatment. Remember, early intervention can often lead to better outcomes, so don’t hesitate to reach out for help if needed.
