Postoperative care after disc herniation surgery?


Hello Doctor, I have a herniated disc at L4-L5 and underwent microdiscectomy about a month ago.
The doctor mentioned that the procedure involved decompression and removal of the nucleus pulposus, and no other materials were implanted.
Currently, when I lie on my back with straight legs, I still cannot lift my right leg high; it starts to feel sore at about a 30-degree angle.
I also feel like I have one leg shorter than the other when walking (it feels like my right leg is being pulled), and at night, I experience heat and numbness in the nerves near my coccyx and in my buttocks, making it difficult to sleep.
Additionally, I have numbness in my right calf and big toe.
The doctor said this is a normal part of the recovery process.
Is this correct? Shouldn't the symptoms improve after removing the pressure on the nerves? Or could it be that I have re-herniated the disc? Should I consider paying out of pocket for an MRI to check my condition? I would appreciate your advice.
Thank you!

Post-discectomy recovery can be a complex process, and it's not uncommon for patients to experience lingering symptoms even after the surgical intervention. Based on your description, it seems that you are experiencing several symptoms that can be attributed to the healing process, nerve irritation, or possibly other underlying issues.

Firstly, it's important to understand that after a discectomy, the body goes through a healing phase where inflammation and nerve irritation can occur. The symptoms you describe, such as difficulty lifting your right leg, feelings of leg length discrepancy, and nighttime discomfort, can be indicative of several factors:
1. Nerve Healing: After surgery, nerves that were previously compressed may take time to heal. Even after the pressure is relieved, the nerves can remain sensitive or inflamed, leading to symptoms like numbness, tingling, or pain. This healing process can take weeks to months, and it's not unusual for patients to experience these sensations during recovery.

2. Muscle Weakness: The inability to lift your leg fully could be due to muscle weakness resulting from disuse or nerve irritation. After surgery, it’s common for the muscles to weaken, especially if you have been less active during your recovery. Physical therapy can be beneficial in regaining strength and function.

3. Scar Tissue Formation: Post-surgical scar tissue can sometimes form around the nerves, leading to symptoms similar to those experienced before surgery. This can cause discomfort and may require additional treatment or therapy to manage.

4. Potential Reherniation: While it’s less common, there is a possibility of reherniation of the disc or issues with adjacent discs. If your symptoms worsen or new symptoms develop, it may warrant further investigation.

Regarding your question about whether you should undergo an MRI, it can be a useful tool to assess the current state of your spine and any potential issues that may be contributing to your symptoms. An MRI can provide detailed images of the soft tissues, including the discs and nerves, and help determine if there are any complications such as reherniation or significant scar tissue formation.

In terms of management, here are some recommendations:
- Physical Therapy: Engaging in a structured physical therapy program can help improve strength, flexibility, and overall function. A physical therapist can tailor exercises to your specific needs and monitor your progress.

- Pain Management: If you are experiencing significant discomfort, discussing pain management options with your physician is essential. This may include medications, nerve blocks, or other interventions.

- Activity Modification: While it’s important to stay active, you may need to modify your activities to avoid exacerbating your symptoms. Gradually increasing your activity level while listening to your body can help.

- Follow-Up with Your Surgeon: Regular follow-up appointments with your surgeon or healthcare provider are crucial. They can assess your recovery, address any concerns, and determine if further imaging or interventions are necessary.

In conclusion, while it is common to experience symptoms during the recovery phase after a discectomy, it is essential to monitor your condition closely. If your symptoms persist or worsen, seeking further evaluation through imaging or consultation with a specialist may be warranted. Remember, recovery can take time, and patience, along with appropriate rehabilitation, is key to achieving the best possible outcome.
