Post-Surgery Numbness: Leg Symptoms After Minimally Invasive Spine Surgery - Neurosurgery

Share to:

After one month of minimally invasive surgery for the slippage and stenosis at the L4-L5 vertebrae, I began to experience numbness in my legs?


Hello Dr.
Lai: I previously experienced difficulty walking with my right leg due to lumbar spondylolisthesis.
At the end of February 2017, I underwent minimally invasive surgery on my lumbar spine, which went very well.
During the month of recovery post-surgery, my right leg felt completely normal, with no pain or numbness.
However, after recently stopping the pain medication and Eucalyn tablets prescribed by the hospital, I have started to feel soreness and numbness in my right leg, whether I am standing or sitting.
Sometimes, lying down for a while helps alleviate the symptoms.
Although my mobility is not severely affected at the moment, I would like to ask the doctor if this could be due to poor peripheral circulation? I am a bit concerned.

Post-surgery numbness and discomfort in the legs, especially after a minimally invasive spine surgery, can be concerning for many patients. It is important to understand that while some level of discomfort can be expected during the recovery process, persistent or new symptoms should always be evaluated by a healthcare professional.

In your case, it seems that after a successful surgery for lumbar spondylolisthesis, you experienced a period of normal function in your right leg. However, after discontinuing pain medications, you began to notice symptoms of numbness and discomfort. This could be attributed to several factors:
1. Nerve Healing: After spine surgery, nerves that may have been compressed or irritated can take time to heal. Even if the surgery was successful, the nerves may still be recovering from the previous compression. This healing process can sometimes lead to sensations of numbness, tingling, or discomfort as the nerves regenerate and adapt.

2. Medication Withdrawal: The medications you were taking, such as pain relievers and muscle relaxants, may have been masking underlying symptoms. Once you stopped taking these medications, the return of discomfort could be a sign that your body is adjusting to the absence of these drugs. It's not uncommon for patients to experience a resurgence of symptoms after stopping medication.

3. Circulation Issues: While it is possible that poor peripheral circulation could contribute to your symptoms, it is more likely that the numbness and discomfort are related to nerve healing or irritation rather than circulatory issues. However, if you have risk factors for vascular problems, such as diabetes or a history of vascular disease, it would be prudent to discuss these concerns with your physician.

4. Postural Factors: Your symptoms may also be influenced by your posture or the positions you adopt while sitting or standing. Prolonged sitting or standing in certain positions can lead to nerve compression or reduced blood flow, which may exacerbate feelings of numbness or discomfort.

5. Physical Therapy: Engaging in physical therapy can be beneficial in your recovery. A physical therapist can help you with exercises that promote nerve healing, improve circulation, and strengthen the muscles around your spine, which can help alleviate symptoms.

6. Follow-Up with Your Surgeon: Since you are experiencing new symptoms, it is essential to follow up with your spine surgeon or healthcare provider. They may recommend imaging studies, such as an MRI, to rule out any complications, such as scar tissue formation or nerve entrapment.

In summary, while some level of discomfort can be expected after spine surgery, persistent or new symptoms should be evaluated. It is crucial to maintain open communication with your healthcare provider, who can help determine the best course of action based on your specific situation. If your symptoms continue or worsen, further evaluation may be necessary to ensure that there are no underlying issues that need to be addressed.
