Post-Surgery Symptoms After Minimally Invasive Lumbar Discectomy - Neurosurgery

More Info

---

After undergoing a minimally invasive lumbar discectomy for a herniated disc at the L4-L5 level, it is not uncommon to experience residual symptoms or new sensations in the legs, particularly in the first few weeks post-surgery. Your report of pain on the outer side of the left calf, decreased sensation compared to the right leg, and numbness in the left foot can be concerning, but they are also part of the recovery process.

When a herniated disc compresses a nerve root, it can lead to symptoms such as pain, numbness, and weakness in the corresponding areas of the leg. During the surgery, the surgeon removes the herniated portion of the disc that is pressing on the nerve. However, even after the pressure is relieved, the nerve may still be inflamed or irritated from the previous compression. This can result in lingering symptoms, which may take time to resolve.

The timeline for nerve recovery can vary significantly from person to person. In many cases, if the nerve was only compressed and not severely damaged, patients may start to notice improvement within a few weeks to months. However, if there was significant nerve damage, recovery could take longer, and in some cases, symptoms may persist. It is essential to maintain communication with your healthcare provider during this period. They may recommend physical therapy, which can help improve strength and flexibility, and may also assist in alleviating some of the nerve-related symptoms.

In your case, the fact that your surgeon indicated that the surgery involved removing the "stone" pressing on the nerve suggests that they believe the primary issue has been addressed. However, the recovery of nerve function can be a gradual process. It is also possible that some of your symptoms could be related to nerve adhesion or scarring, which can occur after surgery. This is where the nerve may become tethered to surrounding tissues, leading to discomfort or altered sensations.

If your symptoms do not improve or worsen over time, it may be necessary to conduct further evaluations, such as imaging studies or nerve conduction studies, to assess the status of the nerve and surrounding structures. These tests can provide valuable information about whether there is ongoing compression, scarring, or other issues that may require intervention.

In summary, while your current symptoms may be concerning, they can be a normal part of the recovery process following lumbar discectomy. It is crucial to follow up with your surgeon or a neurologist to monitor your progress and discuss any persistent or worsening symptoms. They can provide tailored advice and treatment options based on your specific situation. Remember, recovery from nerve compression can take time, and patience is often necessary as your body heals.
