Swelling, pain, and tenderness at the injury site are moderate, though there may be some loss of range of motion. In moderate tearing, some individual ligament or muscle/tendon fibers may be torn completely, but there are still enough other fibers intact for the tissue to retain its integrity overall. In Grade 2 ankle sprains and strains, there is moderate tearing of the affected ligaments or muscles/tendons. Slight bruising or discoloration of the skin may be present, and standing/walking impairment is also minimal. Tenderness, pain, and swelling of the injury site is minimal, but still enough to be noticed upon viewing or palpating (touching).
