Nicely done Charlie! Congratulations and thanks for sharing that experience!
It looks like almost, if not, everything can be repaired or regenerated under the right conditions.
The body is a self regenerating and repairing organism, and science/medicine is very slowly starting to catch up with that.
Ketosis stimulates the regenerative, cellular building and repairative processes of the body. That in combination with your continued running and exercise gave the body the knowledge of which area it should focus on, while also providing the necessary heat and frequent use needed to repair and even improve the area.
While going through this phase of repairing the hip and running for fun; did you notice any significant realizations or alterations with your running posture or gate? Did you notice if the pain unconsciously made you also start changing your running style or movements slightly?
I ask because I’m currently experiencing something similar with my knee and want to get more insight.
