How are the symptoms of L5 nerve pinching different from s1 nerve pinching?

In Brief... L5 supplies the muscles that raise the big toe and foot & provides sensation to the top of the foot. S1 supplies the large calf muscles (those that "push") and provides both sensation to the outside of the foot and innervation for the "ankle jerk.".

If L5 disc was herniated would it cause L5 and s1 nerve symptoms or just l5? Would L5 and SI both have to be herniated to cause those symptoms?

Believe it not--- Herniated L5/S1 disc could cause root symptoms of L5 but not S1, S1 but not L5 (more unlikely), L5 & S1 (common), L4 & L5 (tough but not impossible), or NO symptoms (unusual). With your pain symptoms shooting down the leg an L5 nerve root compression is virtually a gimme. To know if S1 or L4 are affected needs an exam. Wanna talk? www.healthtap.com/drsaghafi. Read more...

Yes as in up to 15%? of people, there can be some "cross wiring" of nerves leading to overlapping patterns of sciatic pain. A disc herniation at L4-5 depending on the size of the herniation and its location can affect several different nerve roots from L3 ( a far lateral or extra foraminal disc herniation for example ) down.
