Well, we will try and help. :mrgreen:
Firstly, what was the reason for the vet visit?
Critical care can be used for dragons, it's quite effective, especially in providing nourishment to sick and malnourished dragons. I've used it quite a bit, and it definitely helps get a dragon who isn't getting the nutrients they need from food, back on track.
Do not do anything to raise the humidity, as this can lead to URI's and other issues.
Really though, we need to know why you went to a vet, what you think is wrong with your dragon, what the vet thinks, etc. The more details the better.
And since I can almost guarnatee you, we are going to need to know this eventually, if you wouldn't mind filling out these questions, they would help.
What
uvb bulb do you use?
What are the temperatures in your tank? The basking surface, hot side, and cool side.
What are you using to measure these temperatures?
What does the daily diet look like, if the dragon is eating?
How often are the bowel movements?
Age/size of dragon?
Any other details you wish to provide, help us better help you.
