I have been dealing with Bilateral posterior sciatica for 7 months now.. My MRI shows bulges and disc tears at L4-L5 and L5-S1. My first injection was after 3 months in L5-S1. Did not help. My second injection was in L4-L5 and L5-S1 three months later and did not help. Finally had the nerve tests last week and the neurologist said I had chronic nerve damage at L4-L5. Yikes. I see my neurosurgeon in two weeks to hear is opinion what to do next. Does anyone have nerve damage with sciatica? Did surgery help the nerve damage and sciatica? I have a feeling that is my only option.
