Foot numbness and lower leg numbness??

My toe started going numb about two weeks ago and has gotten worse as pain in my hip and right buttocks has begun to emerge, I don't think it 's a disc rupture because I do not have lower back pain or lack of mobility. As the pain has grown over the last couple of days I find myself dragging my foot as pain intensifies and the numness has spread.
I do not remember any specific event that caused injury……. It just began to evolve…. what's going on???
