About 2 weeks ago I tripped over a water bottle at home and twisted over the outside of my ankle. This hurt for several days but I thought nothing of it. Then about 4 days later when playing indoor football I fell the same way, except this time without the water bottle. It has been a week now and the inside of my foot and around the back of the inside of my ankle still hurt. Especially when walking/running but also when resting. What might it be and how should I treat it? Btw I am a dancer so could it effect my dancing?
