Hi, with disc herniation is it the worst the herniation is pressing on the nerves the further down the leg it goes? so if it's in the feet it's bad?

Location, location: L5 and S1 nerve root compression or irritation will produce pain radiating all the way down to the feet. (L4 tends to stop at the knee) Where in the back the issue is requires more of a look see as the nerve roots exit the cord at about the L1 spine level then drop down (as the cauda equina) to exit at a lower level of the spine) A disk herniation at L4 can compress any nerve root that passes by
