The fact that you think a "High Ankle Sprain" is a typical, run of the mill, Ankle Sprain, confirms that you have no clue WTF you are talking about.
You should have read the link I posted so you wouldn't look like an even bigger fool.
Here is the dumbed down version for you:
"An ankle sprain and a high ankle sprain differ primarily in the location of the injury, the ligaments involved, and the mechanism of injury. A typical (low) ankle sprain usually results from an inward rolling of the ankle (inversion), damaging the lateral ligaments on the outside of the ankle—most commonly the anterior talofibular ligament (ATFL). In contrast, a high ankle sprain affects the syndesmotic ligaments located above the ankle joint, between the tibia and fibula, and is caused by an outward twisting or rotational force. High ankle sprains are less common (accounting for about 10–15% of ankle sprains) but often more severe, requiring longer recovery times and posing a greater risk of instability if not properly treated."
