Post-Spinal Surgery: Persistent Pain and Numbness in Right Knee - Neurosurgery

Share to:

After spinal surgery, there is pain and numbness in the right knee?


My father underwent surgery on his spine from vertebrae 1 to 5 in mid-May due to nerve compression caused by bone spurs, and the doctor informed us that there was already nerve damage.
If surgery was not performed, he could face further complications in the future.
However, 45 days post-surgery, he is experiencing symptoms of soreness, numbness, and pain in his right knee, which has not improved, and the pain has extended to the thigh muscles.
Should he continue with rehabilitation or see a doctor first?

Post-spinal surgery complications, such as persistent pain and numbness, can be quite distressing, especially when they affect mobility and quality of life. In your father's case, it seems that he underwent surgery due to nerve compression caused by bone spurs, which is a common issue in spinal conditions. The fact that he is experiencing ongoing symptoms like pain and numbness in the right knee and thigh after 45 days post-surgery indicates that there may be several factors at play.

Firstly, it's important to understand that after spinal surgery, the body goes through a healing process that can take time. Nerve tissues, in particular, can be slow to recover, and symptoms such as numbness and pain may persist for weeks or even months after the procedure. This is often due to inflammation, scar tissue formation, or residual nerve irritation from the initial compression.
In your father's case, the symptoms of pain and numbness extending from the knee to the thigh could suggest that the nerve root may still be irritated or that there is some degree of nerve damage that needs time to heal. It's also possible that the surgical site is healing, but there may be other underlying issues contributing to his symptoms, such as muscle tension or compensatory movements due to pain.

Given that he has already undergone surgery, it is crucial to follow up with his healthcare provider. Here are some steps you can consider:
1. Consult with the Surgeon: Since it has been 45 days since the surgery, it would be wise to schedule a follow-up appointment with the surgeon. They can assess the surgical site, review any imaging studies (like MRI or X-rays), and determine if there are any complications such as infection, hardware issues, or nerve entrapment that need to be addressed.

2. Physical Therapy: Continuing with physical therapy is essential. A physical therapist can provide targeted exercises to strengthen the muscles around the spine and improve flexibility, which may help alleviate some of the pain and numbness. They can also teach your father how to manage his movements to avoid aggravating his symptoms.

3. Pain Management: If the pain is significant, discussing pain management options with his doctor is important. This could include medications, nerve blocks, or other interventions to help manage the discomfort.

4. Monitor Symptoms: Keep a close eye on his symptoms. If there are any changes, such as increased pain, weakness, or new symptoms, it is crucial to report these to his healthcare provider immediately.

5. Lifestyle Modifications: Encourage your father to engage in gentle activities that do not exacerbate his symptoms. Activities like walking or swimming can be beneficial, but he should avoid heavy lifting or high-impact activities until cleared by his doctor.

In conclusion, while it is essential to continue rehabilitation efforts, it is equally important to maintain open communication with his healthcare team. They can provide the best guidance on whether to adjust his rehabilitation plan or explore further diagnostic evaluations to understand the cause of his persistent symptoms. Healing after spinal surgery can be a gradual process, and with the right support and interventions, there is hope for improvement.
