What can cause legs, feet & toes pain
, numbness & stinging? History: 13 yrs. ago I woke with intense pain
inside left thigh & outside left lower leg, and I could no longer put weight on left heel without the foot
flopping flat to the floor. Diagnosis was probable herniated disc with siatic nerve damage causing "drop foot
". 2 years ago L4, L5 & S1 were fused.
