When it comes to a situation that seems impossible to resolve, there are several words that can be used instead of stubborn crisis. A difficult predicament, an intractable quandary, or an entrenched issue can all convey the same sense of a problem that seems immovable. An unyielding dilemma, an unrelenting challenge, or a persistent obstacle can also be used to describe a situation that refuses to be resolved easily. Alternatively, a hard-to-solve impasse, a complicated stalemate, or a thorny controversy all describe a problem that requires a great deal of effort, creativity, and perseverance to overcome. Whatever the word used, the key is to keep working towards a solution, no matter what.
