So a couple of years ago I injured one of my ankles. I have no idea what I did. I did all the right things afterwards - rest, ice, compression, elevation - and it got better. However, it has never made its way back to 100%. (In the interest of full disclosure, I should point out that I've never consulted a doctor or a physiotherapist about it, it really wasn't ever all that serious.) I still wear an ankle brace when I exercise, especially for yoga, which is the class I'm most likely to hurt myself in.
(I didn't hurt myself today because I skipped it for no good reason whatsoever.)
Anyway, my ankle was irritating me today, so tonight I did some ankle exercises.
I liked the isometric strengthening exercises and my ankle felt better afterwards.
