A member asked:

2big toes permanently numb for 2 yrs. now my lower spine/back isnumb. the only sensation i feel is pressure.. why?

A doctor has provided 1 answer

Lumbosacral Spine: The nerves that innervate the big toes start from your lower back spine-- i.e., lumbar spine (L4 and L5) and sacral spine (S1). Impingement to these nerves can cause numbing sensations to the dermatomal distributions of the foot or feet.
