My dad (67) has melanoma that metastasized to his brain.  He had surgery to have it removed in October of last year. The surgery went great. He was walking as good as could be because he also had a broken foot at the time. Talking great using his arms eating really good. He started with immunotherapy. Opdivo and ipilimumad. He barely had a side effect. They did a scan and said all of the cancer was pretty much gone. Said he would be on Opdivo for two years. He has been only doing Opdivo treatments for a couple months now, still barely a side effect. A couple weeks ago he began not wanting to eat as well. His health declined fast. My mom took him to the emergency room  yesterday because he could not even stand up.  They said he was severely dehydrated, gave him some fluids, and they came home. They said his brain looked fine his heart looked fine his bloodwork was all really good. This morning he is not any better. He is extremely cold can barely move, can’t stand up on his own and sleeps almost all the time. He has also been vomiting. Could all this be from his treatments or has anyone dealt with this kind of thing before?  It is crazy how sudden he just became so sick. And they say everything looks good. I was just hoping someone would have some insight for me. I really appreciate it. Thanks.  ... View more
