You sound like my twin, only the left side. My pain is very low and goes down the left. I have a tear in my L4-5 and ddd in L5_S1. If you have tried all other conservative things. It is definetly time for a specialist. They may need to do a discogram. That helps them see exactly what disc is giving you trouble.
I am scheduled for a L4-5 lumbar interbody fusion.
Best of luck to you. Happy thoughts coming your way
