I'll try to help:

L5-S1 Mild -moderate disc space narrowing, mildly progressed since prior study. This means that the disc isn't as "fat" as it was -- it's losing it's so-called liquid, so it's drying out. There's a 2-3mm herniation and it combines with facet hypertrophy (overgrowth of bone) to produce moderate right foraminal narrowing. The foramen are the holes that the nerves pass thru to get to the spinal cord. Yours are getting narrow. It also abuts with the right lateral L5 nerve root.

L4-5 Mild degenerative narrowing and dessication (drying out) of the intervertebral disc. Slight anterolisthesis & minimal extradural defect at this level. To be honest, I'm not familiar with anterolisthesis. ????

L3-4 Moderate degenerative disc space narrowing (see above) and dessication (drying out) at this level. There is mild grade 1 spondylolisthesis measuring 2-3mm. This is where the vertebra slips forward over the other vertebra. Small disc bulge.

I'm not a doctor, but have researched this 'stuff' for 28 years. If you have any questions that I can answer, just let me know. I know this is all confusing. From what I can see, this doesn't look like any surgical event. I would think that physical therapy would be a GREAT idea. Therapy can help in MANY cases, and relieve pain. Ask your doc to refer you to a good physical therapist, and one who has a pool as pool therapy is wonderful!

God bless and please let us know how you come out! Hugs, Lee
