I am still suffering from this injury after over 6 months with not much hope of recovery in the near furure.
My advise to you is to cut back on your running and to use that time to determine what may have caused the injury.
Tim Noakes in The Lore of Running says that in almost all cases a injury means a change of shoes.
If your injury is a a relativly new one then this would be my first port of call.
I honestly do believe that the best hope with this injury is catching it early .
Mine hung around untill it was to late for me to find out the root cause so i am now clutching at any straws that i can find.
So in your case (a) Ease of
(b) New shoes
(C) Most importantly, do not underestimate this injury.
Good luck and keep us posted.
