Is it normal to have some lower back pain when coughing or sneezing after microd/hemilaminotomy 3months after surgery? but otherwise there is no pain

Back pain after surg: Spine surgery can lead to scar tissue within the spine. Coughing or sneezing causes increased pressure within the spinal canal. A discectomy leads to weakening of the outer disc wall and is prone to recurrent herniation if subjected to increased pressure. If you combine all these factors, it will be easy to understand why coughing or sneezing can cause more pain. If this pain radiates down the leg.
