A bone bruise is ugly…it takes (what seems like) FOREVER to heal! I used to run a lot and, thanks to knowing how to self-treat, I never really had any problems. Oh, I definitely did get repetitive strain injuries, but I would treat the muscles immediately and it would quickly clear up. Then I did a silly movement and my heel slipped off a curb and came crashing down on the pavement. I didn’t even do it while running….I was just walking and not paying attention to where I was going. I wish I’d been running, the heel of my running shoes would have prevented the injury, but I was in sandals so my heel bone took the full brunt of the injury.
