What is fluctuant?

Fluctuant refers to something that is constantly changing or uncertain. This term is commonly used in the medical field, specifically in regards to swelling or abscesses. A fluctuant swelling is usually filled with fluid or pus, and the fluctuation refers to the feeling of the fluid moving or shifting within the swelling when pressure is applied. In this context, medical professionals may use the term fluctuant to describe the texture or consistency of a swollen area, which can help diagnose the underlying condition and determine appropriate treatment. Fluctuant can also be used in other contexts, such as economics, where it may refer to the ups and downs of a market or the changing value of a currency.
