--certainly what you've got there can explain a lot of symptoms.

The L2 L3 space shows a disc herniation--that's when the disc between the vertebrae is compressed/squeezed sufficiently that material has actually been extruded from it into the spinal space (as opposed to a bulge, in which disc material is being squeezed but not extruding yet). When this material is extruded it can take up space it's not supposed to and press on other structures, particularly nerves. In this case, it doesn't seem as it it's impinging on the spinal cord, though it is compressing the surrounding thecal sac a bit (the "sac" is the canal in which the spinal cord and fluid and connective tissue rests), which is very common. The foramina are the spaces through which the nerve roots, one right, one left (hence the "bilaterally") pass on their way from the spinal cord to the parts of the body they serve; disc material encroaching into this space can crowd or compress the spinal nerve roots, brining inflammation, pain, and neurological deficit.

It seems as if your L4 L5 herniation is worse in that there is definite encroachment of the exiting nerve root on the right side--are you experiencing right leg or buttock symptoms, particularly along the outside of the leg? The L4 L5 distribution runs through that area.
