I had a microdicectomy at l3-l4 on the left side. Right after the surgery my left leg pain went away. Pain came back after two weeks. Put on steroids for a week. Pain is now feels like I’m having a constant leg cramp. My right leg is hurting now just like the left leg. Any suggestions as to why this is happening?
The most common causes of returned leg pain and new symptoms after a microdiscectomy would be a seroma (a collection of post-surgical fluid), a recurrent herniation or simple root inflammation (which would not explain your new onset right leg pain). With failure of relief using oral steroid and what I assume would be some new physical examination findings, a new MRI with gadolinium would be a good next step.
