Then last night, my friend mentioned something that made A LOT of sense. She asked if I'd ever injured that ankle. I have - playing volleyball in college, I sprained it pretty badly. And the place where I sprained it is the place where it swells up the most. She said the same thing happened to her previously-injured knee when she was pregnant.
I have my next appointment on Monday so I'll ask them about it too. For now, though, I've gotten a new setup at work to help keep my feet more elevated:
My ankle already looks better than it did yesterday. I don't know how much of the day I'll be able to work like this but every little bit will help!
