Lower back pain in the L4 and L5 regions can result from disc dehydration, bulging, early degeneration, nerve irritation, or other factors. It is essential to consult an orthopaedic or spine specialist. They can assess the condition of your discs through proper examination and imaging. Once the cause is confirmed, the doctor may suggest pain medication. Physiotherapy can help strengthen your back and core muscles. Posture correction and activity changes can reduce strain on your spine. Further treatment may be needed depending on your condition. You should seek medical help sooner if the pain spreads to your legs or causes numbness or weakness.

Persistent back pain after multiple stenosis surgeries can occur due to factors such as residual nerve irritation, scar tissue formation, muscle weakness, or changes in nearby spinal levels, and it is vital to consult a spine specialist or pain management doctor who can reassess your condition with a detailed examination and updated imaging to identify the current cause of pain, and based on the findings the doctor may recommend options such as targeted physiotherapy to improve muscle support, medication to manage nerve or inflammatory pain, image guided injections if appropriate, or a structured pain management plan. You should seek prompt medical evaluation if the pain worsens or affects your daily activities.
