My husband was diagnosed with cancer of the tonsil and has spread to lymph nodes on one side. he has had 2 induction chemos, 7more weeks of once a week chem and 7 weeks of IMRT radiation. march 10 was his last treatment. Upon beginning the radiation this constant flow of mucous has been the worst side effect. Doctor says it is caused by the destruction of a salivary gland.He spits up every few minutes, eventually gags and then vomits. He is on zofran, lorezapam (sp) and several other meds. He has been hospitalized twice for this and is in the hospital now. He sleeps sitting up for fear of choking. They have given him differrent swish and spits but nothing helps. Any ideas? Can you tell me how long this may last?
