This document describes the symptoms and treatment for a grade 2 ankle sprain. A grade 2 sprain involves a partial tearing of the ligaments in the lateral part of the ankle. Initial signs include moderate to severe pain, swelling, stiffness, bruising, decreased range of motion, and possible instability. Treatment involves RICE (rest, ice, compression, elevation) for two days followed by range of motion and strengthening exercises. Recovery takes 2-6 weeks with treatment and physical therapy.
