All the lumbar ones: Since all the nerves to the legs pass through the upper lumbar levels, these areas if stenosis present, can give you symptoms just like the lower levels when involved.

L4-S1: It's usually L5 &/or s1 nerve roots although hamstring tightness could be due to pars fracture as well.

Sciatic nerve-tibial: Lumbar spine stenosis (narrowing) usually affects all structures below the site of spinal cord constriction. The hamstrings are innervated by a branch (ant. Tibial) of the sciatic nerve (l4, l5, s1, s2, (racepinephrine) s3 origin) the word ham originally referred to the fat and muscle behind the knee . String refers to tendons. The 3 muscles of the posterior thigh: semitendinosus, semimembranosus, biceps femoris.
