Yeah. My insurance said they would only cover it if I got care within 48 hours and, of course, no doctors in network had an opening that soon. I wasn't going to the emergency room two days later because that would cost much more. I just hobbled around on their-store crutches and did everything I could not to move it until the tendons set, then I did range exercises. My ankle was pretty unstable for the last 14 years due to a sprain that never healed correctly but things feel much better this time despite not getting the boot (I tried!).
		
		
	 
Shit, it sounds like we're in the same boat. I have ALWAYS had problems with my ankles. My left one usually took the beating - always twisted/sprained/etc. when I was younger due to skateboarding and soccer. I never really treated it as I should have. Always got back to activity sooner than I should, didn't ice it much, everything that I SHOULD be doing... I didn't. And my parents were too busy working to really keep on me about it. To this day I still have a very weak and sometimes painful left ankle (from Googling, it appears to be some form of peroneal tendinitis). 
I also have high arches, and have gone through the podiatrist route many times for plantar fasciitis.. even to the extent of custom orthotics. My right ankle was in perfect shape compared to the left........... until now. Now my partially busted left ankle feels a hell of a lot better than my right one. I'm definitely older and wiser this time around... so I'm going to try to take care of it. In the meantime, I need a wheelchair and a beer.
