Right Side Abdominal and Back Nerve Sensations: Causes and Next Steps - Neurology

Share to:

Electric, numb, swollen, and prickling sensations appeared in the right side of the abdomen and right side of the back?


Hello Doctor, two years ago I started experiencing electric, numb, bloated, and prickling sensations in the right side of my abdomen and right side of my back.
These sensations became more pronounced when I turned over in my sleep.
After about a month, these symptoms disappeared.
Last year, the same symptoms reappeared for about a month, but due to the pandemic, I did not seek further treatment.
In April of this year, the same symptoms returned and lasted for three weeks.
After a week without symptoms, they have now returned with electric, numb, bloated, and prickling sensations.
I have undergone nerve conduction studies and EEG at a major hospital, which showed no abnormalities.
Could you please advise what might be the issue and if any further tests are needed? Thank you!

Hello Ms.
Ju,
You mentioned that you are experiencing electric, numb, swollen, and prickling sensations in your right abdomen and right back.
Your symptoms may suggest an abnormality in the lumbar nerve roots.
A common cause is nerve root compression, but a minority of cases may present similar symptoms due to postherpetic neuralgia.
Symptoms of peripheral nerve compression include:
1.
Pain characterized by burning and electric sensations.
2.
Symptoms that have a specific dermatomal distribution, which can be triggered by touch or pressure.
3.
Accompanied by muscle soreness and weakness.
Examinations for peripheral nerve issues typically involve electrophysiological studies to assist in diagnosis:
- Nerve conduction studies: to measure the conduction velocity and waveform of large fiber nerves.
- Electromyography (EMG): to assess muscle response in the areas supplied by the affected nerves.
I recommend that you visit a neurology outpatient clinic for further evaluation.
You may want to consult a physician with expertise in peripheral nerves, as they have more experience with EMG testing.
Thank you for your inquiry.
If you have any related questions, feel free to discuss further.
Wishing you good health and peace.
Dr.
Jiang Junyi, Neurology Department, Taoyuan Hospital

The symptoms you are experiencing, which include electric, numb, swollen, and prickling sensations in the right side of your abdomen and back, can be quite complex and may arise from various underlying causes. Given the recurrent nature of your symptoms and the fact that they have persisted over a significant period, it is essential to consider a multifaceted approach to understanding your condition.

Firstly, the sensations you describe could be indicative of nerve involvement. The right side of the abdomen and back is innervated by various nerves, including those from the thoracic and lumbar spinal regions. Conditions such as nerve compression, irritation, or entrapment can lead to the symptoms you are experiencing. For instance, a herniated disc in the lumbar region can compress spinal nerves, leading to pain and abnormal sensations radiating to the abdomen and back. Similarly, conditions like thoracic outlet syndrome or even peripheral neuropathy could contribute to these sensations.

Another possibility is that your symptoms may be related to musculoskeletal issues. Muscle strain or ligamentous injury, particularly if you have engaged in physical activities that could have stressed these areas, can lead to referred pain or abnormal sensations. The fact that your symptoms seem to worsen with certain movements or positions, such as turning in bed, supports this idea.
Additionally, visceral pain from internal organs can sometimes present as referred pain in the back or abdomen. For example, issues with the kidneys, liver, or gastrointestinal tract could manifest as discomfort in these areas. Given your history as a carrier of Hepatitis B, it is also prudent to monitor liver health, as liver-related issues can sometimes present with abdominal discomfort.

Since you have already undergone several diagnostic tests, including ultrasound and X-rays, and have not found any abnormalities, it may be beneficial to consider further evaluations. An MRI of the lumbar spine could help visualize any potential disc herniations or nerve root compressions that may not have been evident on X-rays. Additionally, a comprehensive evaluation by a neurologist or a pain specialist may provide further insights, especially if nerve conduction studies and EEGs have not revealed any abnormalities.

In terms of management, if your symptoms are indeed related to nerve irritation or musculoskeletal strain, physical therapy may be beneficial. A physical therapist can provide targeted exercises to strengthen the core and back muscles, improve posture, and enhance flexibility, which may alleviate some of your symptoms. Additionally, modalities such as heat therapy, ultrasound, or electrical stimulation may provide symptomatic relief.

Lastly, it is essential to keep a detailed symptom diary, noting when the symptoms occur, their intensity, and any associated activities or positions. This information can be invaluable for your healthcare provider in determining the underlying cause and tailoring an appropriate treatment plan.

In conclusion, while your symptoms may stem from nerve involvement, musculoskeletal issues, or even visceral pain, a thorough evaluation and possibly further imaging studies are warranted. Engaging with a multidisciplinary team, including neurologists, physical therapists, and possibly pain specialists, will be key in managing your condition effectively. Always consult with your healthcare provider before making decisions about your health and treatment options.
