I'm dealing with a bit of an odd injury: My left ankle is bothering me, but only only when I walk, not when I run. Basically, at the start of each run I might feel a bit of a sharp pain in the ankle for the first few strides, but then it goes away (it's not painful enough that it changes my gait, as far as I can tell). It's almost as if the ankle is a bit stiff and just needs to get loose. I also experience the pain later in the day after periods of inactivity (when I get off the train to work, when I get up from my desk). I usually wear boots to work, and get the feeling that they might be exacerbating the pain, so I wore sneakers today, and while the ankle is still acting up, it's not as bad as usual.
Normally with an injury I'd just take a few days off, but since it's not bothering me while running, I'm not sure if this would do any good. Anyone ever experienced anything similar and have any advice? I was thinking that some ankle stretches might do the trick.
