Brian mentioned that if you did not have foot problems prior to the surgery than you need to definitely go back to the neuro and tell him of this symptoms along with the others. The foot dragging sounds like something called "foot-drop". I have this on my left side. It's from the nerves not working correctly. If your neuro has no answer or is reluctant to pursue this, perhaps you could get a referal to a neuro who specializes in Perpheral Neuropathy. It sounds as if you may have some issues with this.
