SWELL SPOTS, CURVED, EACH The Curved Swell Spot is primarily used for hard-to-accommodate areas, like the ankle and patella. We've also received feedback from several therapists and professionals that indicates this little pad is also very effective when used under bandages around the elbow, for inferior breast scarring, and to direct lymph flow around scars in any areas of the body. Recently, this spot has been used behind the ear and around the eye for facial swelling as well.
