What happens when you sprain your ankle?
The most common ankle sprains are the inversion type, where your foot is turned inward at an extreme angle. When you sprain your ankle, there is tearing of ligaments that connect your leg to the bones in your feet. Severe sprains may even cause fractures in the leg or foot.
Ligaments, once torn, usually never regain the same strength again. Proprioceptors, which help with your balance, in the ankle joint also lose some of their function. This leads to poor balance and a higher risk of re-spraining that ankle.
