Herniated disc
Hello, Doctor: I just had surgery for a herniated disc two days ago, specifically at the L5-S1 level.
This is my third surgery; the previous two were at the L4-L5 level.
Before this surgery, my main symptoms were pain in the right buttock radiating down to the thigh.
Immediately after the surgery, the pain symptoms disappeared, but I still feel like there is a tightness in the right thigh and calf, and I cannot exert force with the right forefoot; I can only rely on the right foot to support my body.
Could this be due to prolonged nerve compression from before, or is it a sign that the surgery was not completely successful? Additionally, is it standard practice for the hospital to perform a CT scan immediately after surgery to confirm its success? (A CT scan was done before the surgery, so one should also be done afterward, right?)

After lumbar disc surgery, not all symptoms will necessarily resolve immediately.
This is because the surgery itself only removes the herniated disc that is compressing the nerve, without directly affecting the nerve itself.
Therefore, if the nerve has been compressed for an extended period or if the symptoms are severe, it may take some time to recover even after the surgery.
Thus, as long as there is an improvement in symptoms post-surgery, the procedure can be considered successful.
It is only when there is no improvement or if symptoms worsen after the surgery that further evaluation or treatment is required.

More Info
After undergoing lumbar disc herniation surgery, particularly at the L5-S1 level, it is not uncommon to experience a range of symptoms during the recovery period. Your description of immediate relief from pain in the buttock and thigh, while still feeling a sensation of tightness or pulling in the right thigh and calf, is something that many patients report. This can be attributed to several factors, including nerve recovery, muscle tension, and the body's healing process.
Firstly, the sensation of tightness or pulling in the thigh and calf may indeed be related to the duration of nerve compression prior to surgery. When a nerve is compressed for an extended period, it can lead to changes in the nerve's function and the surrounding muscle tissue. Even after the source of compression is removed, it can take time for the nerve to heal and for normal function to return. This phenomenon is often referred to as "neuropraxia," where the nerve is temporarily affected but can recover over time.
The inability to exert force with the right foot could also be linked to muscle weakness or atrophy that developed while the nerve was compressed. Muscles can weaken when they are not used properly, and it may take some time and rehabilitation to regain strength and coordination. Physical therapy is often recommended post-surgery to help strengthen the affected muscles and improve overall function.
Regarding the surgical success, it is essential to understand that while the immediate relief of pain is a positive sign, complete recovery can take weeks to months. Surgeons typically assess the success of the surgery through clinical evaluation and may use imaging studies, such as MRI or CT scans, to confirm that the herniated disc has been adequately addressed. However, routine post-operative imaging is not always performed immediately after surgery unless there are specific concerns or complications. The decision to conduct follow-up imaging often depends on the surgeon's protocol and the patient's symptoms.
In your case, if you continue to experience significant symptoms, it is crucial to communicate these to your healthcare provider. They may recommend further evaluation, including imaging studies, to ensure that there are no complications, such as residual disc material or other issues affecting the surgical site.
In summary, your symptoms may be a combination of nerve recovery and muscle weakness due to prior compression. It is essential to engage in a structured rehabilitation program to facilitate recovery. If symptoms persist or worsen, follow up with your surgeon or a physical therapist to discuss your concerns and explore further treatment options. Remember, recovery from lumbar disc surgery is a gradual process, and patience is key.
