Every time I take part in an exercise(basketball, tennis, etc..) that requires extensive lateral movement and even sometimes after a rather long run the outside of my foot works it way from a uncomfortable feel to a crippling pain that requires extended periods of time. It is such a pain that I can hardly walk immidetialey after and even some the next day. Eventually, I lay off of it and it is back to normal completely around 2 days later. I ve looked for solutions on line but they are very vague and need more guidance! I also have a rather high arch. I m not sure if that s relevant but hope that helps!
