Peroneal Tendon injury

Options
Hey runners (bikers, swimmers, etc),

I've been noticing that the outside of my ankle has been bothering me and when I looked it up online it seems to be where the peroneal tendon is on the outside of my ankle. Is this a common running injury because I've only noticed it since I've been trying to increase my speed over the past few weeks. Any thoughts/suggestions for healing are appreciated. I'd like to tell you I'm going to stay off it, but I'm trying to train for a Sprint Tri this summer. Yikes.
