Refractory chronic cough (RCC) is a cough that continues even after common causes have been evaluated and treated, or one that remains without a clear explanation after a full medical workup. RCC is thought to involve cough hypersensitivity, which means the nerves that trigger coughing become overly sensitive and react to otherwise harmless stimuli such as talking, laughing, strong smells, or cold air. Understanding more about RCC and the treatment approaches being studied may help you feel more informed and more confident when speaking with your healthcare team.
