If your husbands mouth sores are from the radiation, the sores should not be there permanently. It just takes time to heal. For most patients, they can never recover as fast as they think they should. A major contributing factor in all of this is his intake. After what your husband has been thru it can take a full 2 years for his body to bounce back. Every single day he should be taking in 2500 calories and 48-64 oz of water. I also suggest having a long chat with his physician, specifically asking about radiation mucositis.
