Re: 5 level fusion done....still have SCIATICA!!! WHY?
Welcome to the board. As you know, a five level fusion is a very big surgery...one most surgeons do not want to have to attempt as statistically the rates for success are not great. How was the fusion done, posterior or ...?
Which levels were included?
Have you had a MRI since the surgery to see if there is still any nerve compression?
Unfortunately, it may be that the nerve is permanently damaged and may still be sending out pain signals even though it is technically no longer compressed. But since you recently had the surgery, it is really too early to jump to that possibility.
Since you have had laminectomies through the years, I am assuming you have had sciatic pain for a long time. If a nerve has been compressed for a long time it can take an equally long time to regenerate or recover...up to two years, according to some doctors. Also, with a multi-level fusion, everything seems to take longer, the time to fuse, recovery in general.
I'm maybe not understanding what exactly you had done, but usually sciatica is caused by nerve compression created by a bulging disc, stenosis, facet arthrosis or spondylolisthesis. When you say your spine is now "straight," I'm not sure what you are referring to.
In any case, five months post surgery is still early. Are you taking neurontin or lyrica for the nerve pain? I would suggest asking for a MRI at your next appointment if you haven't had one yet. There may be a problem with the hardware. Have you had any steroid injections since the surgery? This is often done when there is lingering nerve pain post surgery.
