Hi Brian and everyone, thank you for responding.
The thing is my sister had radiation 2 years ago, started to get better and she now has the worst sores down her throat than any of her other sores before this. Its been 3 months and no relief, losing tons of weight and can barely eat. Drugs and even steroids aren't helping at all. I am hoping that with the feeding tube, if she decides to get one, she can give her throat a break to heal because eating must be irritating it even more.
