Experiencing Numbness in Left Buttock When Sitting or Lying Down? - Neurology

There is a patch of numbness on the left buttock when sitting down or lying down?


Hello, doctor.
Since the beginning of this year, I have been suffering from "suspected" autonomic nervous system dysfunction...
I have asked many questions, and I appreciate your patience in answering them! However, there are still two symptoms that persist.

1.
Occasionally, my muscles twitch, mostly at the extremities of my hands and feet.
It feels like an involuntary contraction.
I have seen a neurologist, but the doctor did not provide a clear answer to my question and just said it was fine.

2.
For the past two months, when sitting or lying down, I experience a tingling sensation in a specific area of my left buttock, which comes and goes.
Recently, I have also felt a slight tingling sensation while standing.
Is it necessary to have an X-ray for further examination? Thank you!

Dr. Jiang Junyi reply Neurology


Hello: Your symptoms are more indicative of sciatic nerve root compression, which is caused by a herniated disc that compresses the cervical nerve roots.
If the first sacral nerve root is compressed, it can lead to a tingling sensation in the buttocks.
It is advisable to lift heavy objects in smaller increments.
When placing heavy items on a higher surface, it is best to use a ladder or stool to avoid lifting.
When dealing with tasks at a lower level, try to lower your body instead of bending at the waist to reduce nerve root compression.
I recommend consulting a neurologist or physician for a nerve conduction study.
Wishing you good health and peace.
Sincerely, Dr.
Tao, Neurology Department.

More Info


Experiencing numbness in the left buttock when sitting or lying down can be concerning, and it's important to understand the potential causes and appropriate steps to take. Based on your description, it seems you are dealing with symptoms that could be related to nerve compression or irritation, possibly stemming from issues such as a herniated disc, sciatica, or even muscular tension in the piriformis muscle.

Numbness in the buttock area, particularly if it radiates down the leg, can often be attributed to the sciatic nerve being compressed or irritated. This can happen due to various reasons, including a herniated disc in the lumbar spine, which can protrude and press against the nerve roots. Additionally, the piriformis syndrome occurs when the piriformis muscle, located in the buttock region, spasms and compresses the sciatic nerve, leading to similar symptoms.

Given that you have been experiencing these symptoms intermittently, it is advisable to consult with a healthcare professional, particularly a neurologist or an orthopedic specialist. They can perform a thorough physical examination and may recommend imaging studies such as an MRI or X-ray to assess the condition of your spine and surrounding structures. While X-rays can provide information about bone alignment and any degenerative changes, MRIs are more effective in visualizing soft tissues, including discs and nerves.

In terms of treatment, there are several non-invasive options available that can help alleviate your symptoms. Physical therapy is often recommended to strengthen the muscles supporting your spine and improve flexibility. A physical therapist can guide you through specific exercises aimed at relieving pressure on the sciatic nerve and improving your posture, which may help reduce numbness and discomfort.

Additionally, you might consider incorporating stretching and strengthening exercises into your routine. Focus on stretches that target the lower back, hips, and glutes, as these areas can contribute to nerve compression if they are tight. For instance, gentle piriformis stretches can help relieve tension in that muscle and potentially reduce nerve irritation.

If your symptoms persist or worsen, your doctor may discuss other treatment options, including medications for pain relief and inflammation, such as NSAIDs (non-steroidal anti-inflammatory drugs). In some cases, corticosteroid injections may be considered to reduce inflammation around the affected nerve.

It's also important to pay attention to your posture when sitting or lying down. Ensure that your sitting position is ergonomic, with your feet flat on the ground and your back supported. Avoid crossing your legs for extended periods, as this can contribute to nerve compression.

In summary, while it may not be necessary to have an X-ray immediately, consulting with a healthcare professional is crucial to determine the underlying cause of your symptoms. They will guide you through the appropriate diagnostic tests and treatment options tailored to your specific condition. Remember, early intervention can often lead to better outcomes, so don't hesitate to seek help if your symptoms continue to affect your daily life.
