I did the clinic in October too. I did have some issues with my feet, did have the sore calves, and all the stuff you can think of. However, most of these things I was convinced were due to wrong technique and not relaxing lower legs.
I think that shin pains are due to landing in front of GCM and/or active landing.
I worked hard on technique and form (still do) and each time after running I'd try to find trigger points (muscle knots) in my lower legs and feet and massage them. I found out that I had trigger points in my lower legs (in my flexor digitorum Longus to be precise) that were causing feet pains as well. These knots were mainly caused by not keeping the ankles relaxed. After I corrected my technique the pains went away.
Anyhow, I got rid of all pains and aches and sorenesses. During running I can feel when I lose form and am able to correct myself.
So, what I am saying is that you should probably have a good look at your form and technique. Maybe have Christine Chen take a look. Make sure you are relaxed while running (that's the hardest part) and as soon as you loose form, stop, do drills, and run again, etc.
