Injured bluetonge wont eat

Question
Hi, I have a injured bluetong lizard that I havent been able to get to eat.   My dog had the lizard and I saved it from the dog but it had a big gash from the middle of its head to its top lip and lost a bit of blood.  The gash in the head has now scabbed over but I have been unable to get it to eat or drink.  It just seems to want to sleep all the time and its full summer here so that isnt right. I have tried putting it back where it lives in the garden and left it there for a day and it just closed its eyes and went to sleep and barely moved, I was hoping that since it was wild that if I put it back and the damage was scabbed and wouldnt get an infection that it would find an insect and go back to normal but no such luck. Over the years I have had multiple lizards and dragons as pets so am comfortable with them and havent really come across the problem of one not eating.  I was thinking that because the gash went to its lip that it may be too sore to eat but after 7 days I am starting to think something else could be wrong.  I have noticed that one of its eyes it out of wack and has dropped in the socket so could this be a brain damage or something?  Any assistance or advice would be fantastic.  I live in Victoria and all the decent vets are swamped at the moment with the bushfire animals and I have found from experience that most of them dont really have much of a clue when it comes to lizards.

Answer
 I would contact the Victorian Herpetological Society.  They would probably even have specialists as members that can help you.  You friend must be very traumatized to sleeping in summer.  I'm doing the winter bit here in the US, New York specifically.
  Since there is a head injury involved, it may take a while to heal, and reptiles do get headaches. Dropping an eye would be a sign of head injury which is serious in any creature.  Your friend needs more definitive care than home first aid, so the VHS would be your next best contact if vets are so occupied.
