The MRI report is relatively reassuring. It shows mild disc bulges at L4–L5 and L5–S1, but importantly no nerve-root compression. It also mentions straightening of the lumbar spine with paraspinal muscle spasm. Mild disc changes on MRI do not always correlate with the amount of pain a person experiences.
Since you are having pain involving the back, right hip and both legs with difficulty walking, the MRI alone is not enough to determine the cause. A clinical examination of the spine, hips, sacroiliac joints, muscle strength, sensation and reflexes is needed.
Next Steps
Consult an orthopaedic/spine specialist or physical medicine specialist for an in-person examination. If there is no neurological deficit, treatment is usually conservative initially, with appropriate activity, physiotherapy/exercise and pain management rather than surgery.
Health Tips
Avoid prolonged bed rest and avoid heavy lifting until evaluated. Seek urgent medical attention if you develop increasing leg weakness, numbness around the groin/saddle area, loss of bladder or bowel control, or rapidly worsening difficulty walking, as these can indicate significant neurological involvement.
For this patient: the MRI does not currently show a surgical disc problem; because he specifically says walking is difficult and both legs are involved, I would recommend an in-person neurological and orthopaedic examination rather than simply treating the MRI report.
