Return nerve pain after a microdiscectomy can originate from three issues; nerve inflammation, re-herniation or seroma formation.

The most common is inflammation. The nerve root when decompressed, can swell. Any activity (like walking) can stretch the root. When the root swells, some return of symptoms can be expected. It is a matter of time before the swelling recedes and the root “feels better”.

Re-herniation can occur and can happen to 10% of individuals who have a herniation (no matter if surgery occurred or not). Symptoms are generally more severe than inflammation above but don’t necessarily have to be. Typically, there will be an activity or motion that causes an immediate pain that does not improve with time.

Finally, seroma formation can occur. A seroma is a fluid-filled pocket at the surgical site that develops after surgery. This is actually a very common occurrence but typically does not cause symptoms. On occasion, after activity, this fluid pocket can expand and cause pressure symptoms.

Recognizing any of these conditions requires a repeat MRI with gadolinium. Before a new MRI is ordered, I will give the patient an oral steroid to reduce inflammation. If that treatment is not effective, depending upon symptom severity, I will order an MRI.

Thankfully, escalation of symptoms is rather uncommon and does not need to be addressed with most patients.

I endorse any activity that reduces symptoms and does not cause rebound increase of symptoms later that evening. I think swimming is just fine.
