Persistent Leg Pain and Burning Sensation After Spinal Surgery: Next Steps - Neurosurgery

Numbness and tingling in the left foot accompanied by a burning sensation on the dorsum of the foot?


Dear Dr.
Lai,
I have an 82-year-old elder at home who has been experiencing numbness in the left leg (from behind the left knee to the sole of the foot) for about ten years.
Additionally, there is a burning sensation on the dorsum of the foot, making it difficult for them to stand or sit for long periods, which exacerbates the numbness and heat, severely affecting their quality of life.
Two months ago, they underwent an MRI at the hospital, which revealed severe compression at the fourth and fifth lumbar vertebrae (there was no space between the vertebrae).
Consequently, the doctor performed a decompression surgery on the fourth and fifth lumbar vertebrae.
Post-surgery imaging showed that there is now a significant space where the compression was, appearing almost normal, and the doctor indicated that the surgery was very successful.
However, two months have passed, and all symptoms have not improved at all.
I would like to consult with you regarding the following:
1.
After the surgery, the symptoms of numbness and burning sensation have not improved at all.
Could there be other possible causes for this?
2.
We reside in New Taipei City.
Are there any recommended hospitals, doctors, specialties, or treatment options that could provide further care for the elder?
I appreciate your valuable time and assistance!

Hello: Based on what you mentioned: 1.
After the surgery, the symptoms of soreness and burning sensation have not improved at all.
Are there any other possible causes? 2.
We live in New Taipei City; do you have any recommended hospitals, doctors, specialties, or treatment methods for the elderly to continue their treatment?
Response: 1.
First, recheck the MRI to confirm whether the main symptomatic segment is truly decompressed and free of any pressure.
If it is decompressed, we need to evaluate whether it could be diabetic neuropathy, peripheral vascular disease, or adhesions due to nerve clots, among other issues.
2.
If the above recommendations have been followed and there is no possibility of further surgery, you might consider lumbar injections or radiofrequency ablation (a minimally invasive outpatient procedure for lumbar pain nerve block).
You can consult a neurosurgeon or a pain management (anesthesiology) specialist nearby.
Best wishes.

Lai Chao-Kang, Chief of Spine Neurosurgery, Changhua Hospital.

Hello, thank you for your detailed description of your elder's condition. It sounds like a challenging situation, and I appreciate your concern for their well-being. Let's address your questions regarding the persistent leg pain and burning sensation following spinal surgery.

1. Post-Surgical Symptoms: The fact that your elder has not experienced any improvement in symptoms such as leg pain and burning sensation after the decompression surgery is concerning. There are several potential reasons for this lack of improvement. First, it is essential to consider that while the surgery may have successfully relieved pressure on the spinal nerves, there could still be residual nerve damage or irritation that has not yet healed. Nerve regeneration can be a slow process, and it may take time for symptoms to improve. Additionally, the symptoms could be related to other underlying conditions, such as peripheral neuropathy, which can cause similar sensations in the legs and feet. Other factors, such as vascular issues or diabetes, could also contribute to these symptoms.

2. Further Evaluation and Treatment Options: Given that the symptoms have persisted for two months post-surgery, it would be prudent to seek further evaluation. A follow-up appointment with the surgeon who performed the decompression surgery is advisable to discuss the ongoing symptoms. They may recommend additional imaging studies, such as an MRI or CT scan, to assess the surgical site and ensure there are no complications, such as scar tissue formation (adhesions) or other issues that might be causing the symptoms.

In terms of treatment options, if the symptoms are indeed related to nerve irritation or damage, a multidisciplinary approach may be beneficial. This could include:
- Physical Therapy: A physical therapist specializing in post-surgical rehabilitation can help develop a tailored exercise program to improve strength, flexibility, and function while addressing pain management.

- Pain Management: Consulting a pain management specialist could provide additional options, such as nerve blocks, medications (like gabapentin or pregabalin for nerve pain), or other interventions to alleviate discomfort.

- Neurology Consultation: If the symptoms persist, it may be helpful to consult a neurologist who can evaluate for any neurological conditions that may be contributing to the symptoms.

3. Recommended Facilities: Since you are located in New Taipei City, there are several reputable hospitals and specialists you can consider. Hospitals like Taipei Medical University Hospital, National Taiwan University Hospital, and Chang Gung Memorial Hospital have departments specializing in neurology, orthopedics, and pain management. It would be beneficial to seek referrals from your primary care physician or the surgeon to find the right specialist for your elder's needs.

In conclusion, while the surgery may have been successful in relieving spinal compression, the persistence of symptoms suggests that further evaluation and possibly additional treatment are necessary. It is crucial to keep an open line of communication with healthcare providers and advocate for your elder's health to ensure they receive the appropriate care. Thank you for your dedication to their well-being, and I wish you both the best in navigating this challenging situation.
