By way of explanation, a high ankle sprain is an injury to the ligament that joins the two lower leg bones, the tibia and fibula, at the level of the ankle. It destabilizes the ankle much more than a lateral ligament sprain (although those can be serious also). Really severe high ankle sprains sometimes require surgery if very unstable.
The big issue is healing time. Lateral sprains can be anywhere from a few days to 3-4 weeks to return. High sprains can be double that, 3-8 weeks, or longer.
Heres hoping it’s not too long.
