Hi. I had spinal stenosis and lumbar laminectomy 12 years ago, and I'm going through the same thing now at age 62. The first time, after the MRI, I was scheduled for surgery a couple of weeks later and nothing was done before it. (The surgery was extremely helpful, and eliminated my pain the same day.)
This time, they're recommending an EMG test and a steroid injection in my spine before the surgery. The latter is partly to buy time and partly because the results of the injection are useful for the surgeon to know. (That's what they tell me, anyway.)
In 2006 I had a brain tumor removed, and they gave me oral cortisone before and after surgery to keep the brain swelling down. I kept begging the doctor to stop the cortisone because it gave me pretty bad anxiety and insomnia.
The point is, I haven't found any mention of spinal cortisone as having these side effects of oral cortisone, but I wanted to know since it would likely stay in my system for a long time. Any answers? Thanks.
