Torn or severed ligaments, detached bone structures, and breaks make what may initially appear as a simple level two sprain something much more serious. Level three sprains also carry the risk of additional significant injuries farther up the leg and within its deep muscular tissue. The tissue between the two leg bones is torn as a result of a twisting action coupled with the failure of the ankle to remain stable under stress. It takes weeks, sometimes months to heal. Treatment Any sprain with moderate swelling and pain should be X-rayed immediately and examined by a doctor as soon as possible.
Pressure is kept off.
Keep treating the injury in this way as long as there is swelling. But don't apply heat in between. Normal room temperature will allow restoration of blood and nutrients. Elevation - Keep the foot elevated to allow excess fluid to drain. Moderate movement, preferably under the supervision of a doctor of physical therapist, will help restore full range of motion.
