I had an epidural injection 2 wks ago and it did not work. I was wondering if I should go for the 2nd injection. I have spinal stenosis in lumbar spine. Before that I had taken dexamethasone orally and that did nothing for the pain. Had an x-ray recently an it showed I have a slip vertabrae.
You have spinal stenosis and your X-ray also shows slip vertebrae. Epidural injection generally helps in such cases but not in all cases and results are very variable. Some get relief from pain for long and some get relief for short duration and some don't get any relief. If you are not relieved with it once it can be tried again. Depending upon the amount of stenosis further management will be done.
