What is the rationale for elevating a second-degree ankle sprain above heart level?

Elevating a second-degree ankle sprain above heart level is primarily aimed at preventing further edema, which is the accumulation of fluid in the tissues. When an ankle sprain occurs, the surrounding tissues may become inflamed due to injury, leading to increased blood flow and fluid accumulation. By elevating the injured area, gravity aids in the drainage of excess fluid, thereby reducing swelling and facilitating a better healing environment. This practice is part of the R.I.C.E. (Rest, Ice, Compression, Elevation) protocol commonly used in the immediate management of sprains and strains. Maintaining elevation helps to minimize the chances of increased swelling that can hinder recovery and exacerbate pain.
