How bad is recovery from an oral mass surgery. My vet just sent Bam Bam home with long term pain medication for an oral mass. He had a tooth extraction last week and has not been doing good. They could not tell during the extraction if it was infection or a mass. Now she thinks it us a mass. She didn't think the surgery was ideal for him, bit she doesn't even sound 100% completely sure it is a mass. She is just recommending pain medication until he stops eating. I am looking to get a 2nd opinion because she didn't even say why the surgery was not ideal for him. He is 14 years old, is it his age?
