Pitting Edema:

When a swollen area is pressed, the pressure leaves an indentation (pit) that takes time to fill back in.

Pitting edema can be demonstrated by applying pressure to the swollen area by depressing the skin with a finger. If the pressing causes an indentation that persists for some time after the release of the pressure, the edema is referred to as pitting edema. Any form of pressure, such as from the elastic in socks, can induce pitting with this type of edema.
