Hi, thanks for writing to HCM.
All your findings and symptoms in the description suggests that you have lumbar disc disease
with spinal canal
The most common symptom in spinal canal stenosis is leg pain precipitated or made worse by walking and relieved by rest.
The initial management is non-operative (which is not so successful) and includes antiinflammatory medications and Epidural steroid
If the symptoms fail to respond, then a surgical decompression is needed.
Hope this information is helpful. Good day
