Suggest Treatment For Cuboid Fracture

I fractured my left cuboid and 2 1/2 weeks ago as a result of dropping a 20-25 lb long board on my foot at the joint. I'm in a boot but now my toes, knee and leg feel numb and tingly as well as the arm on the opposite side of my body. Is this normal? I'm more uncomfortable now than I have been since I broke the foot.
