@XxSepiorxX , I didn't want to respond here because I don't want you to feel like we are ganging up on you, but I keep coming back to the tread to read what others are saying and I agree with their overall thoughts.
A vet can't fully understand what is going on internally without a full workup and most importantly some x-rays. We are just going from the visible signs and after seeing the evidence that you have also pointed out...
you can understand our view. I would not wait a month if at all possible and see if you can get to a vet with more experience with these animals. You could call and ask a few questions first before making an appointment just to see if they have experience with MBD and chameleons. That way you will know the visit will be a productive one.
I truly hope your chameleon gets the help he needs and can have a great quality of life in your care! There have been many success stories of people of all ages dealing with MBD and I'd love to see you on that list!
