Thanks for putting x ray findings.
In grade 1 and 2 spondylolisthesis
does not require surgery.
But if you have severe radiating pain
in lower limbs get mri spine done. If disc space is narrowing too much you may need surgery.
you should take injection metadac and arachitol after visiting orthopaedic surgeon
Other symptoms can be relieved by medication for a while.
Get well soon.
