My grandfather was receiving chemotherapy last week and the nurse messed up and he received a bottle of medicine in 15 minutes, that normally takes 45 minutes to an hour. During which he lost his speech, but it came back in 5 minutes. Now he is having problems with his sight and his mouth is still numb. Do I need to find another Dr. or what? I know the symptoms are related to the mess up, and I just need some suggestions....Thanks
