Lower back pain (LBP) after microdiscectomy is somewhat common for about 6-12 weeks post surgery. LBP can last up to 6 months after surgery and 10% of patients can develop permanent LBP. There is a small percentage of patients that can have a low grade infection causing LBP. It might be worth getting labs to look for infection or even a new MRI.
