Thanks for writing to us.
It seems to be due to compression of nerve roots at lower back which causes radiation
of pain to lower limb(radiculopathy
).A physical examination is necessary to find out the exact cause.
You need to consult an neurophysician who will advise you an MRI
scan of the spine to assess nerve root compression
Hope this will helps you
Wishing you good health...
