Lower Back Pain. Foraminal stenosis.

I injured my lower back 3+ years ago. I'm 26, injury occurred at 23. I received an MRI that was not done correctly 3 years ago. I just received MRI results for the second time. The doctor suggested I go to a well know PT guy. When I arrived at PT, the doctor looked at my diagnosis and believes that it is not fully recoverable. I've had constant minor pain/soreness with recurring severe pain. Here is what the results state. I thought maybe someone could explain thoughts so I could better understand next steps. L4/L5 - There is a foca central/right central disc herniation at L4/5 with some intrinsic signal heterogeneity in keeping with annular fissuring posteriorly. There is mild associated central canal stenosis. There is mild left and moderate right subarticular stenosis with mass effect and mild impingement of the descending right L5 nerve root. There is crowding of the descending left L5 nerve root. There is mild bilateral neural foraminal stenosis.
