How it's used
This term is the standard colloquial way to refer to a canker sore in Hong Kong. It is often associated with the concept of heatiness in traditional Chinese medicine, so people frequently blame it on eating too much fried food or not drinking enough water. You will hear it used almost exclusively with the verb 生.

Common mistake
Do not confuse this with 痱子, which is the Mandarin term for heat rash on the skin. Using the latter in a Cantonese context will cause confusion as it refers to a completely different medical issue.
