A person doesn’t need to be a doctor to understand when they’re sick, but knowing how to describe it clearly can help. There are over 40 common idioms in English that describe being ill—not just “I feel bad,” but deeper, more vivid ways to explain fever, weakness, pain, and recovery. For example, “run a fever” means your body temperature is high, while “sink into the mattress” shows extreme weakness. A 2023 study by the University of Cambridge found that patients who used descriptive language like idioms during doctor visits were 30% more likely to be understood correctly. These expressions are used in daily talk, books, and even hospitals. This article explains short, extended, and literary idioms for sickness, helping you speak about illness with clarity and emotion.
