My mother was diagnosed w/ Stage 4 lung cancer which spread to the brain last month. She is going for her second kemo Wednesday of this week. She has not had any nausea from the kemo however her feet are extremely swollen and it is working its way up her legs. The Dr.'s say its the medication that keeps her swollen but it is worrying me. We ruled out blood clots today but wanted to know if anyone had a similar experience or have any solutions. Also she has the soars in her mouth that make it hard for her to eat or drink...can anyone make any suggestions? Thanks for your help.
