Hey, I m a skateboarder, who is used to rolling ankles once or twice a year. About 2 years i ago i twisted my left ankle for the first time ever, (twist not a roll) and 2 years later, i can feel a sharp pain sometimes when i walk, and sometimes my ankle will even give out. This isnt the normal pain i usually feel from an ankle roll. It could be a high sprain, and if it is, how can i properly rehab it without leaving work?
