Swollen ankle (affected side)

About 2 and a half weeks ago, my left ankle (affected side) was the size of a melon.  I was so excited to go running and be active. I unfortunately; was running with two now to be considered after thinking about it; an old pair of running shoes that I should of upgraded awhile ago. I love running. Also; what girl does not love shopping for shoes? I started looking now; as I realized that might be the issue. I believe that the reason it affected my left ankle more is because of the gait and limp with my affected side. My right ankle was not affected. My left shoes had worn down and a tear was starting in the left shoe too.  It took from a Monday to a Friday to go down in swelling. It did not hurt but it looked bad. I finally bought a new pair of shoes. 

Advice;
When you need new shoes; get new shoes. Do not wait like I did. This is the last time I do that. It took 5 days for my swollen ankle to go down and be normal again.
