I thought it was because I tripped over and landed
hard on it. Now it's fine, but my right foot
is sore, especially if I've been sitting on one position for a long time, then as soon as I set my right foot, it's sore, it seems like I have to give it time to adjust. It feels like I have a misplaced bone somewhere... coz once I clicked my foot, or massage it, then it's fine again. I can run, walk fast with no problem. If I've been on my feet for the whole day it's not a problem too.
