I have dessication of discs at L5-S1 and due to herniation of discs there is lot of pain in left side of leg mainly in leftvbuttock and below hoto knee. And partial loss of sensation on 3rd and 4th fingers on left foot. Due to this slipped discs I am facing lot of discomfort mainly in last 2 months. The sciatic pain was mild earlier fir past 8 months and now it is too much. Do I need to undergo surgery, are there alternate options available?
