Lumbar X-ray suggests degenerative changes at L5âS1 which can explain the back pain radiating to the left leg; since symptoms are persisting an MRI LS spine is advised for proper assessment of nerve compression. Short-term medicines like pregabalin and NSAIDs are appropriate for nerve pain, but corticosteroids should be used cautiously in diabetics as they can raise blood
sugar and should not be continued long-term. Prolonged bed rest is not recommended; once acute pain reduces, guided physiotherapy and back-strengthening exercises are essential. Surgery is considered only if MRI shows significant nerve compression or if pain and weakness do not improve after adequate conservative treatment.
