Pulled muscle: I'm not an orthopedist, but i suspect you pulled a muscle or tendon. The obvious solution to pain while running is to substitute a different form of exercise for awhile. If the pain persists you should see your doctor or an orthopedist.

Shin splints: Tibial stress rxn stress fracture get it looked at once healed workout consistantly avoid peaks and valleys of activity choose swimming cycling elliptical instead of running.
