Scar vs Herniation. Given that you recently had a laminectomy, you could have re-herniated in the same area or developed scar tissue in the area causing pressure on the nerves that exit the spine. I would consult your surgeon to discuss you options, you may need new imaging to see if any changes have taken place.
No although in a few. Pain can persist for a few days to several weeks postop if there is some ongoing inflammation that can be managed by medication. Otherwise, get evaluated to make sure that a disc fragment was not missed or you may have even had a recurrent disc herniation. Sometimes scar tissue can cause pain after surgery but this happens weeks after the surgery as the scar forms. If smoker, results are poor.
