what do these results mean?

MRI results show:
  l3-4 mild disc bulge no herniation mild degenerative changes and mild neural foraminal narrowing
  L4-5 stable left lateral and foraminal disc protrusion partially encroaching on the exiting leeft L4 nerve root. Mild left neural foraminal narrowing. Minimal facet joint degenerative changes
L5-S1 a moderate right lateral disc protusion which contacts and compresses the right S1 nerve root. THis does not contact the thecal sac. There is no evidence of central canal stenosis or neural foraminal encroachment.

I am 54 years old. Recentlly developed severe burning pain down right leg. Dr. prescribed flexeril, lodine, prednisone and vicodin. They take the edge off the pain. I am scheduled to see a pain management dr on 5/27 after I complete physical therapy, which started today. Right leg is weaker than the left per physical therapist. Will this improve or continue to get worse? Is therre any other treatment options?
