Bearded Dragon recently broke its tail...

Question
As the subject states, my beardie recently broke it's tail. It was probably the last inch, and it's now fallen off. Now my beardie has became very sluggish, and not eating or drinking. He has also started to kind of "seizer"... If that's the right word, but it's whole body shakes, and it's hard to calm down.
Do you have any suggestions?

Answer
 Get him to a good reptile vet right away.  He may have gotten an infection and if it has gone to far up the tail, it may not look good for him.  Get him to a proper vet...except no other substitutes, like pet store people who rarely know anything about reptiles. And get him to the vet as soon as possible.
