Definition
疑难 is a noun meaning 'difficulty' or 'problem'. It is most frequently used as an attributive modifier before nouns like 问题 (question) or 杂症 (disease) to describe something complex or hard to solve — think 'knotty issue' rather than a simple 'difficult' adjective. You'll see it in formal or medical contexts, such as 疑难杂症 (difficult and complicated illnesses).
