Question every timeline of running again after injury

What does it mean when your doctor says you might be able to run in 3 weeks, depending on what your x-rays shows? If your doctor guesses that in three weeks, you're going to have something appear on an X- Ray, that assumes the bone is going to be stronger at that time you get the x-ray. Right?  So what that also really means is that until three weeks from today, every single day, healing happens. Tissues are getting stronger. More collagen is forming. The osteoblasts and osteoclasts are working in conjunction to remodel the bone. More bone is getting laid down. Tissues are getting stronger.  But every single day, if you get stronger, then in theory, every single day, you could do a little bit more activity.  Today on the Doc On The Run Podcast we’re talking about why you should question every timeline of how long it's going to take to get back to running after an injury.
