Thanks for posting your query.
You are suffuring from PIVD at l5/s1. Due to this Disc bulge pressure occurs on nerve
roots & radiation
of pain occurs in that dermatotome. Physiotherapy
like intermittent lumbar traction , back exercise reduces pressure of disc bulge for some time & gives relief.
According to severty & patient demand surgery is a good option (Discectomy
). Nowadays Microdisectomy done with an operating microscope. Exposure is very limited. Morbidity & hospitalisation is less.
So you can consult an orthopaedic or neurosurgeon for detailed examination and discuss about surgical options.
Wishing you good health.
