I think I injured my left ankle.

I'm not sure if I have a stress fracture or strain or sprain, or what. I started feeling stiffness and pain in it about a month ago. I'd feel it when started out on my runs. The pain would go away after about 5 minutes of running, so I thought I just needed to stretch it out more beforhand.

But every time I ran after that, the pain was increasingly worse at the beginning and would last for longer. I took a break from running for about a week, and when I started running again, the pain was at the same level I left it.

Late last week, the pain started lasting throughout my entire run, though it would decrease a bit after the first 10 minutes. Now, whenever I wake up during the night and in the morning, my ankle is pretty stiff. It loosens up after a minute or two of walking on it.

Whatever I've done to my ankle, I probably shouldn't run on it for about a month or more. And that sucks 'cuz I really like running, and was counting on it to help me lose my last 3-5lbs. I guess I'll look into a brace...
