In this condition lumbar spinal canal is narrowed which leads to compromise in blood supply to traversing nerve roots. So at rest everything seems normal but when you start working increased requirement is not met and pain starts. Diagnosis is confirmed by MRI of lumbosacral spine which can be old one from radiology center nearby you. Meanwhile, start tab regain x 75 mg twice a day. Tab ibuprofen 400 mg thrice a day for pain relief. Please take opinion from spine surgeon nearby you with reports. </s>
