瘩背

痩背 (dābèi) refers to a large, infected boil or carbuncle, typically a painful skin infection caused by bacteria. It is more severe than a regular boil and often requires medical attention.

The character 瘩 (dá) means 'boil' or 'abscess,' while 背 (bēi) literally means 'back.' Together, they form a term that specifically describes a large boil on the back or a similar body part. The term may have historical roots in traditional Chinese medicine terminology.

In daily use, 瘩背 is commonly encountered in medical contexts or discussions about skin conditions. It is important to distinguish it from smaller boils, as it is more serious and may require treatment with antibiotics or drainage by a healthcare professional.
