Will 3 weeks of bed rest heal a stress fracture?

Today's question comes from someone who watched the YouTube video on the Doc On The Run YouTube channel called “How long before I can run with a stress fracture.” The comment was: “Thank you so much for this video. I want to ask if resting for three weeks, complete bed rest and I can afford to do this because I am a student, and it is summer holiday then I can walk to my college to do daily normal tasks. I do not do any physical training or running and my college is about a kilometer away.” Will three weeks of bed rest heal a stress fracture?  Well, that is a great question and that is what we're talking about today on the Doc On The Run Podcast.
