What I’ve learned is that if the person is conscious and knows who they are and what happened, then it's not necessary to call an ambulance. But in cases of bleeding and vomiting, then it is necessary. That's why I couldn't sleep because I needed to be 100% sure he wouldn't have a headache. Yes, that's true; after waking up, it's good to stretch your hands, then slowly sit up, and then stand. So if you do that, it's good :) My king is better now, just in pain, but I see on his face he's happy that his wife brings everything to his feet 😂
