I had a microdiscectomy at L5S1 in March. I was recovering nicely until about 2 months ago when I started having back pain again. They did an MRI and told me that I had a bulging disc at L4 of little concern, L5 was definitely narrower than it was before the surgery, and the vertebrae around L5 had (intraneural?) edema. The edema is what they say is causing the new bout of back pain. I haven't really been able to find much about it on the internet. On the MRI, it appears as a giant chunk of white on the vertebrae above L5.
Does anyone know the prognosis for this? Is it permanent? What causes it? When the doctor was telling me about it, it sounded like I was doomed to this back pain forever, but don't other types of edemas typically heal?
Also, I have periodic (3/wk) whole leg muscle spasms, but only at night. It gets worse if I drop my neurontin down. They think this is atypical for back injuries, but I wasn't having them before the surgery. Does anyone know what causes it and how I can stop them?
Any help is greatly appreciated.
