Pain is severe in the right side lower back moving through the thigh & left leg means the
nerve root is getting compressed by the extruded disc. This condition may be treated with rest,
physiotherapy and exercises for some time, but eventually, he will require surgery.
Disc Bulge where Annulus is not torn can be managed by conservative treatment
But
Disc Extrusion, where
Nucleus Pulposus is extruded and is pressing on the neural components require surgery sooner or later
Hope you found the answer helpful.
