Ankle Swollen & Pain

Lately, I've been experiencing some slight swelling in my right ankle (of the dropped foot) which in turn, I think, has been causing me some ankle pain.  I have noticed it mainly when I am on my feet more, which makes it hard to walk.  Not only am I thinking about raising my foot, I am now thinking about the pain I am going to experiencing every step I take.  Even though I am longer in physical therapy, I still feel as though my foot is still making progress.  I just don't see the numbers anymore.  I wish someone could measure it for me! I'm wondering if I am experiencing the swelling and pain since I am so close to a "possible total foot drop recovery?"   I'm going to estimate that my foot drop will be completely recovered by December 2014.  The month that the EMG doctor estimated total recovery to me one year ago (but he told me December 2013!).
