Post-Microdiscectomy: Persistent Numbness in Buttocks and Feet Explained - Neurosurgery

More Info

---

Post-microdiscectomy persistent numbness in the buttocks and feet can be a concerning issue, especially in older patients like your mother, who is 71 years old. It is important to understand that while microdiscectomy is a common procedure to relieve nerve compression caused by herniated discs, the recovery process can vary significantly from person to person.
The numbness your mother is experiencing may be attributed to several factors. First, it's essential to recognize that nerve recovery can take time. After surgery, the nerves that were compressed may have sustained some degree of damage, and while the pressure has been alleviated, the nerves may still be in a healing phase. This can lead to persistent symptoms such as numbness, tingling, or weakness in the affected areas.
Another possibility is that the numbness could be related to the surgical procedure itself. During surgery, there may be some manipulation or trauma to the surrounding tissues, which can lead to inflammation and irritation of the nerves. This inflammation can cause ongoing symptoms even after the primary issue has been addressed.
Additionally, if your mother had pre-existing conditions such as diabetes or vascular issues, these could also contribute to nerve damage and slow down the recovery process. Vitamin B12 deficiency, which is common in older adults, can also lead to neuropathy and may exacerbate her symptoms.
To address your concerns about how to potentially shorten the nerve repair time, there are several strategies that may help:
1. Physical Therapy: Continuing with a structured physical therapy program can be beneficial. A physical therapist can provide targeted exercises to improve strength, flexibility, and range of motion, which may help alleviate some of the symptoms.

2. Medication: Sometimes, medications such as gabapentin or pregabalin can be prescribed to help manage nerve pain and discomfort. Discussing these options with her physician may provide some relief.

3. Nutritional Support: Ensuring that your mother is receiving adequate nutrition, particularly vitamins that support nerve health, such as B vitamins, can be beneficial. A healthcare provider may recommend supplements if dietary intake is insufficient.

4. Patience and Monitoring: It's crucial to monitor her symptoms and maintain regular follow-ups with her healthcare provider. Nerve recovery can take several months, and while it can be frustrating, many patients experience gradual improvement over time.

5. Alternative Therapies: Some patients find relief through alternative therapies such as acupuncture or chiropractic care. While these should be approached with caution and discussed with her physician, they may provide additional options for symptom management.

In conclusion, while persistent numbness after microdiscectomy can be distressing, it is not uncommon. The recovery process can be lengthy, and various factors can influence the healing of nerves. It is essential to maintain open communication with her healthcare team to ensure that her recovery is monitored and that any necessary adjustments to her treatment plan are made. With time and appropriate care, many patients do experience significant improvement in their symptoms.
