1 Bottom of foot pain may occur if the sciatic nerveâs S1 spinal nerve root is affected. 2  Typical symptoms of pain in the bottom of the foot may include weakness in the gastonemius muscle, making it hard to walk on the tiptoes, raise the heel off the ground, or even complete everyday activities like walking or driving.
Structural issues related to the pelvis and spine -- such as stenosis or spondylolisthesis -- can also trigger sciatica. Sciatica typically affects one leg. Sufferers may feel sharp pain, numbness, tingling and possibly weakness along the leg, calf and/or toes. If bowel or bladder incontinence or a âfoot dropâ occurs (so you can't lift your foot up), get to the doctor ASAP.
