Hello,
I have posted about my recent P-LIF on my l5-s1 approximately 3 months ago. Right now I suspect I have now herniated my l4-l5 which has been found to be extremely bulged for the past 3 years.
In my previous herniations of l5-s1 I really did not have a lot of back pain (rarely rate back pain more than a 1 on the pain scale).
Now with this new problem I am wondering…..
Now that there is a cage at l5-s1 and if there is a herniation at l4-l5 could the back pain be due to the inflammation caused by the fusion and the l4-l5 herniation causing general back pain? Or is it more likely the back pain would be caused by the herniation of l4-l5 alone or the back pain would be caused by the healing fusion?
Hope that makes sense?
I assume you underwent a fusion at L5-S1 for multiple recurrent disc herniations. Patients with herniations causing leg pain and not back pain are generally not “wired” to have lower back pain.
Discs however are very capable of causing lower back pain. If you had an already significantly degenerative disc at L4-5 and have returned to the same activities as prior to the fusion, you could have certainly caused further degeneration to the L4-5 disc.
However, if your back pain started three months after your fusion at L5-S1 and you never had back pain before, I have suspicions of a pseudoarthrosis (lack of fusion) or delayed fusion at L5-S1. X-rays including flexion/extension are the first steps to determine this. Your surgeon can determine this possibility.

Does that sound right to you?
Also, after my follow-up MRI to check for my pain they did not find any herniation of l4-l5 but apparently they say cervical spondolylosis. Right now, since I did not herniate l4-l5 we are going to do an EMG next week to test my nerves; but if there is no herniation at l4-l5 I am worried something wrong with the nerves because what I am feeling is nerve pain.
They have started me on gabapentin which makes me happy, because narcotics are not what I need I need something specific to nerve pain.
Is it unusual for them to report cervical spondylosis from an MRI of lumbar spine?
Fusion images at three months should demonstrate some bone growth but if the surgeon did not use BMP (bone morphogenic protein), it can occasionally take more time to demonstrate fusion bone.
An EMG is not a very useful tool in my opinion if there is no motor weakness or peripheral neuropathy (both from my understanding you do not display).
The report of “cervical spondylosis” is probably a misdictation from the radiologist as he meant to say “lumbar spondylosis’ which means degeneration of the lumbar spine which is obvious.
