My 73 year old grandfather became incredibly unwell 2 days ago, he had extremely sever pain in his mid back (left side), was very pale and vomiting. He was ok yesterday, he actually seemed 100% better, however, today he woke and could barely move out of bed, his pain is back, he was very pale again and has been vomiting again, however he has spent nearly the entire day in bed. I am very concerned, and getting him to the doctor can be extremely hard as he is so stubborn and has a "she'll be right" attitude. Can anyone please offer any advice. Thanks in advance.
