I do feel a difference. I can run in place with no pain but jogging while landing on the heel still hurts a little. Running on the toes is less pain, particularly when tightening the ab. I'm still at least 4 weeks away from any meaningful running or sprinting. It still hurts to simply hold a bent knee hanging ab lift, but I can do full lunges without pain.
In addition, I'm doing stair stepper aerobic machine - every other or 3rd day. I feel very out of shape and weigh about 150 lbs... but I intend to change that soon. I'm hoping to do a big hike on Sun will be having an MRI Monday to rule out any other possible injuries. My next Drs. appointment will be a week from Mon.
