SWELL SPOTS, PALMAR SMALL, EACH The Palmar Swell Spot is primarily for use on the volar surface of the hand. This little spot works wonders under edema gloves and bandages, and is great for the concave shape of the palm. The design makes this spot great for usage on the dorsum under compression gloves. It also addresses lumpectomy scarring by tucking into a bra over the scar.
