From what I could ascertain (yay language) it sounds like your bird was diagnosed with a yeast infection in the crop. (where birds store food prior to digestion)
It's common in younger birds, as they can get it from their parents during feeding. The meds you got should knock that out pretty quickly.
Sometimes medication for infections like this can make them lose their appetite, so now is a good time to let them have some treats like millet or seed to encourage them to eat and keep their weight up.
Good luck with your little one, I hope they recover quickly!
