This is probably too late to help but those in the Philly area might find the info useful. Dr. Nick Romansky is a podiatrist that comes highly recommended from several runners I know. He is one of the docs for the US Women's Soccer Team. He has helped me with shin splints and has kept many a marathoner healthy. His number is 610-933-8644 (and no, I am not affiliated with his practice--I just know how hard it is to find a doc who will give you more helpful advice than rest & ice).
