I think it would be helpful if you saw a physio. But you should try and strengthen your core so while you're runnning some of the workload will be taken off your legs.
Hope this helps.
Try eating foods like ginger and lemon tea, parsley and devil's claw, all good natural inflammatorys. Try getting the muscles rubbed out by sports massage therapist and after training be sure to drink your milk and eat protein for recovery. Calcium allows the two filaments in the muscle fibre two slide and release ATP.
