Lumbar Spondylosis

I just had an MRI and trying to read the results and It says at L3-l4: Mild posterior bulge. Mild facet degenerative changes with ligamentum flavum hypertrophy. Mild central stenosis. No forminal narrowing.
L4-L5Broad circumferential bulge. Advanced facet hypertrophic spurring with ligamentum flavum hypertrophy and bilateral subarticular narrowing. Moderate sentral stenosis. Mild bilateral forminal narrowing.
L5-S1: Severe loss of disc height with endplate changes and interspurring circumferential annular bulge demonstrated. Moderate facet hypertrophic spurring. Moderate central stenosis. Bilateral foraminal narrowing

Lumbar spondylosis and facet degenerative changes. Findings are most pronounced at L4-L5 and L5-S1 with moderate central stenosis and bilateralforaminal narrowing.

What does this mean cause my back , hips and thighs and legs and left big toe is numb and hurting  and I can hear and feel disc rubbing on disc when I move , knees get weak and sometimes fall down , still working but  its hard, what should I do? hurts to exercise.

Hi
Thanks for writing to the forum!
You definitely have a problem at the lumbar spinal region causing pressure on your spinal nerves. Hence you feel those neurological symptoms. You would need surgery based on the report you have pasted. However a neurologist is the best judge who can clinically co-relate the reports. Please consult one ASAP. You should not ignore this at all.
Hope this helps. Please let me know if there is any thing else and do keep me posted. Take care!
