Hi! My mom had cancer surgery on her tongue in September 2008. She lost half of it. The doctor says she's OK now ,but she still has constant pain . Is there something to help her? She says the pain stops only when she sleeps. Besides, she lost the sensation of her left ear, because the doctor took away 60 ganglios from the neck. Also she 's very thin. She's 75 years old. Thanks for your help.
