How it's used
Refers specifically to long term, deep seated health issues that are difficult to resolve. It is almost exclusively used in the compound 痼疾 to describe a persistent ailment or a metaphorical deep rooted problem. You will rarely hear the single character 痼 used alone in modern speech.
Examples
He has some chronic illnesses and is always feeling unwell.

Common mistake
Do not confuse this with 固 which means firm or solid. While they share a similar sound in some contexts, 痼 is strictly reserved for medical or metaphorical chronic conditions.
