I would recommend a trip to the vet. Regurge is not a good sign. I've had several WC animals over the years and sometimes force feeding is necessary to get them hungry/going. I have never experienced a single regurge in all my years of keeping chondros.
What size meal did you force feed in relation to the animal. For adults, I usually start with a f/t or f/k hopper mouse for a first assist feeding. I dip the mouse in egg whites to help get it into the throat. Not only does it help with feeding, but it also adds a bit more nutrients.
What are the temps?
What is the sex and approx. age?
Where is the animal located.....such as a secluded room or a high traffic area?
Has a fecal test been done?
WC animals are usually pretty easy in my experience. IMHO, there is something keeping it from wanting to feed. If you have a male, it could just be typical male fasting. I'm sure there are others that can come up with more questions to try to help you answer your question.
