My mom, aged 80, has completed 6 brachy+27 radiotherapy for a tumor on her right lower gum one month ago. While she has recovered from peeling skin on the neck and the bleeding and sore mouth has become ease and she can eat congee and porridge now, NEW PAIN develops on the membrance on both sides of her cheek. More worrying is: white lines occur on the left side (far side from radiotheray), burning pain on near side and a line of small water bubble develop on upper palate after meals. Besides, one month after therapy, she still feels a lot of heat releasing from her mouth and lip. Can someone tell me is this the normal side effect of radiotherapy or it means new infection? I read about the article on Candida on this website and wonder is this the cause for her new discomfort?
