Son had surgery August 18, his problem now is severe swelling and lots of pain when he tries to eat. The duct from the saliva gland was cut and he was told the pituitary gland has to learn to shut down the saliva gland. He is out of the hospital and has had to go on a liquid diet, even smelling anything cooking will make his face swell. No answer from the Drs. about how long it will take. Has anyone else experienced this and have any idea of how long it will take to stop producing saliva???
