No, it did not turn up overnight. The snake has been in respiratory distress since I acquired her. My vet, who has nearly 20 years experience with herps has run some diagnostics in attempts to determine the underlying problem. The snake shows signs of RI, and is being treated for RI; however, she is void of normal symptoms (mucus, froth, etc) associated with RI. To confirm the Chondroma lateral x-rays and a procedure similar to a tracheal intubation are needed.
