Though the report is not complete but still what I can make out from the report is that you have degenerated disc at L5-S1 level
If you have not tried conservative treatment before than take muscle relaxant and anti inflammatory medicines
Physio in the form of SWD and IFT
Avoid prolonged sitting, sitting on floor or bending forward to lift heavy weight
Next Steps
If all this does not help or there is pain in leg also, visit the clinic for further evaluation and management
