MRI Results- What does it mean??

[NeNe]

Hello,
I just got back from my dr and was given the results of my MRI. I am just going to type the "Impression".

Lumbar Spine MRI -
1. Right L5-S1 posterolateral disc herniation abutting the right S1 nerve root as it exits from the thecal sac.
2. Left lateral disc protrusions at L3-L4 and L4-L5 impressing on their respective spinal nerves in the foramen.
3. Disc bulging and discogenic disease from L1-L2 through L5-S1

If I could get some sort of answers as to what this all means, I would REALLY appreciate it!!

Thank you!!
