A severe sprain can be immobilizing as a broken bone and sometimes, just as painful.
Signs and symptoms of a sprain: swelling, pain and discoloration. Direct tenderness such as a specific point and apparent deformity could mean a fracture instead of a sprain.
Ankle sprains are most common and approximately 80-85% of those are from rolling the ankle outward while the foot rolls inward.
Treatment for ankle sprains: RICE principle.
Rest: keep weight off affected area.
Ice: use ice to reduce swelling. If ice is not available, use a cold damp cloth and wrap it tight around ankle.
Compression: Tape sprained ankle to support it.
Elevation: Keep elevated which reduces fluid buildup in the affected area.
