Ihave surface numbness on back of lft upper thigh, lft side foot and heal.  EMG came back negative for nrv dmg the numbness is not constant. The MRI states large cnetral and left lateral disc extrusion at L5-S1 with a marked effacement of the dural sac as well as posterior and lateral displacement of the proximal left S1 nerve root.  I currently have no major back pain but I can not stand on my left toes from a flat footed position.  My right foot I can.  Muscles in the calve and thigh feel like i just rubbed out a charlies horse.  Soft tissue message is helping muscle mobility, but with the negative emg i do not understand why I am experiencing numbness still.  My current doctor does not know either.  Now is is sending me to a podietrist to see about lifts in my shoes.  I am confused and not sure where to turn.   Thank you
