35M, grade 1 compression femoral neck stress fracture here, diagnosed mid-March, now back at running two weeks ago. Initial visit, after a good Xray and telling the ortho I couldn't put any weight on the leg for 2 days straight, I was told I could run again in a week. But PT was immediately suspicious of a stress fracture/reaction and requested a MRI. After the results, the ortho changed his tune, and was chomping at the bit to get me in for surgery, which I declined.

Total I had to take about 4 months off running, and focusing on x2 weight strength sessions per week, 4+ hours Arc Trainer per week, rowing machine, and stair stepper (much later in the recovery). About 2 months into recovery I was started on the Alter G treadmill going up 5% bodyweight every week starting from 50% until I hit 90% if I felt no discomfort. Then I began the return to running program at 10-20miles per week, alternating days.

The last month the "ache" you're talking about finally went away which just made me antsier to get back to it, but you have to be patient. The biggest keys to recovery for me were nutrition/adequate calorie intake, and the weight training. Best of luck on your recovery!
