Answer
 Hi Mike.  Dragging legs can be from impaction, injury, or a neurological problem.  It would be best to have him seen by a good reptile veterinarian.  This way he gets a definitive diagnosis.  And impaction can be caused by too large prey as well as particulate substrate so it is still in the running.  Have him seen as soon as possible.  If you don't know of a good exotics vet, there is a directory of vets who specialize in reptiles and amphibians at www.arav.org.
