SWELL SPOTS, DORSAL LARGE, EACH The Dorsal Swell Spot was originally designed for use on the dorsum of the hand or foot. This shell-shaped spot works well to address this stubborn area of swelling when used under low stretch bandages. People also find it easy to use when placing it under their edema glove or compression garment. The Dorsal Swell Spot is available in both small (typically used for the hand) and large (typically used for the foot).
