I’ve taken my budgie to the vet multiple times already and they still haven’t been able to get a clear diagnosis. Right now he is being tested for PDD for the second time. He was fine for a few weeks but recently went to the vet for Onsior. Since then he’s been back to vomiting every few days. Today is especially bad as he hasn’t stopped vomiting even with the Reglan I gave him. He is also super restless and keeps walking up and down his cage. He is also severely itchy and keeps scratching his head vigorously on the cage bars and stick. At this point I’m not sure what to do as the vet has not been very helpful at all and even mentioned euthanasia.
