Foot / Ankle Issues

For the past two weeks or so, I've been having some pain in my right foot.  Not sure what I did to aggravate it, but its frustrating.  Its along the outside of the foot as indicated in the picture.  I found that I'm landing on that area when walking or pushing off it when walking instead of across the entire front of the foot. Part of it likely stems from my the injury to the joint, however I struggled and worked hard in physical therapy after the  injury/surgery so I would walk without a noticeable limp.  In trying to figure out the issue, I've noticed that my foot is turning out as its normal position.  I'm going to have to stay more conscious of what is happening when I walk.  I may need to get new shoes.  I'll need to examine the treads to see if it is wearing unevenly.
