I do that. Sometimes I think it's more that the bones are out of place, but other times it feels like I snapped or overstretched something. Totally incapacitated, but then suddenly it's fine. I don't get that! I did develop bursitis in my wrists and in my heels that took FOREVER to get better though. My wrists are one wrong move away from being back in braces again, I can just feel it that they're not completely better.
I turn my ankles all the time and it never even bothers me. It usually scares other people around me, certain that I'm going to need to go to the hospital, but then they're shocked that I just keep on walking. I did turn it bad enough a few weeks ago that I bruised the TOP of my foot on the pavement. It was sore for about 15 minutes and then I was fine. So my foot bruised, but my ankle never swelled or anything.
We rode a "sky ride" at the amusement park last spring and you have to kind of jump off and move aside quickly, I guess kind of like a ski lift. My son and I both felt like our feet broke and we almost fell to the ground. Neither of us could walk for several minutes, but then our feet were fine the rest of the day. I described it to my friend like if you imagine two trains hitting head on and then all the train cars crashing together, sliding in between each other, etc. Seemed like such a gentle ride, something I could do, since I can't do spinny rides or roller coasters anymore. It was great until the very end!
