Fell on hip again. Blahhhhh. Was very clear to me this time that when I started to be off balance I stood up instead of getting lower/dropping a knee. Will keep that in mind for next time.
Marking myself as recovered bc I successfully went for a run without the swelling bouncing around, but would hurt worse than original fall if I fell on it again (so not fully recovered to go to roller derby practice).
Resolution is time, and will be wearing padded shorts and doing things at low speeds until it's fully recovered to fall on again!
