lower back pain

Hi,
I ve been suffering lower back pain since April last year. I was diagnosted with the following:

-Annular tear

- L5/S1 disc degeneration with mild loss of height and a small shallow focal bulge posteriorly.

- Small focus of increased marrow signal anteriority around the L2/3 disc level.This is not specific but does raise the possibility of an early "Romanus lesion"/

I have had a Caudal Epidural and a Discogram with no positive result, also 10 session of physio.

I am in a lot of pain, Any advise of what I could do to feel better?

They have advised surgery.

I would appreciate any response.

Regards
Junior
