My husband finished radiation three weeks ago. He is still having tremendous pain in his mouth, from the sores caused by radiation. He is just so frustrated and sick of being sick. I see him losing more and more weight. He wantst to know when it might get better. When does the hurting stop? He also seems to have an extraordinary amount of phlem in his nasal area that is causing him to spit ALL THE TIME. Has anyone been through this and can you give us some idea of when things might get better? Thank you.
