My brother was diagnosed with stage four lung cancer and throat and now is in his brain. He was doing chemo but just had his first radiation treatment day before yesterday and he said he doesn't want to do it. He feels horrible. He was walking fine now he can barely make it to the door from the couch. He has indigestion really bad after anything he eats, so basically he is throwing anything he eats. He has no energy at all. And he keeps mentioning vibration. He said his whole body just vibrates. The vibration comes and goes. I'm not really sure what I wanna ask Yall ...... He's just my favorite brother he's such a wonderful guy he's funny and it's heart wrenching that he just got funnier since all this ... He's so strong ... He keeps telling me don't worry it's ok. I'm ok. Any reply at all would be so appreciated.
