question: 2 months ago, my arch started having some pain off and on.  I'm teaching in China this year and do a lot of walking.  Recently, it started having more pain with the walking.  This week the pain moved up into my ankle and even aching in my leg.  I see swelling in my ankle.  What can I do to help it stop swelling and relieve the pain.  I am on my feet quite a bit and won't return to the US until July.
