Ah yes if I didn't make it clear sorry and thank you for answering my question~ how about the rest?

약이 오르다 is closer to 화가 나다 bcuz they both are internal. And i hardly think 약이 오르다 is interchangeable, but it works too. People will get it. This is my first time here so i don't know if the additional details are also your question or not. Sorry if it's not yours
