Falling on ice

I crashed on my affected hip 2 nights ago when rain froze on the sidewalk in front of my apartment. Having fallen on that hip numerous times I need to know exactly how many more times I need to do that to make sure it is strong enough for when I fall when I'm really old. It took me a while to realize why my neck muscles were sore, I tightened them up enough to prevent my head from crashing to the ground. And each one of those falls probably strengthens those bones, similar to the stresses boxers put their hands through so they don't break bones when fighting.

I expect your doctor should have an EXACT PROTOCOL on that. Or how is your doctor strengthening your bones?  When I was trying to ride a two wheel bike I crashed on my left hip numerous times. One time going to a doctor who had it x-rayed and said it seemed to have microfractures. He had nothing to treat it so I just hobbled around for the next week.
