Wow, you've gone for changing your running style? I hope it works for you. I had 4 months away from running initially, then ran through August, but the pain never went completely. I have done nothing since the beginning of September due to the pain. I am a postman and I reckon that due to me walking 6 miles a day every week for 5 days, this is maybe why I'm not any better. A new job may cure me!
