So I've had this problem for a while and ask about it in various circles over the years but have never gotten a good answer...
When I jog a part of my calf muscle becomes exhausted, very tight and burns (likely from lactic acid) very quickly. On the order of within several minutes of jogging. This happens if I walk quickly too. The name of the muscle is
peroneus longus.
This has always stifled my running because long before any of my other muscles get tired or I get winded I am forced into a limp from this little guy running down the side of my calf. It's all flexed up and is hard as iron. When I finish the jog it'll be in a lot of pain and only after an hour+ of rest will it relax. (Cold showers/ice/elevation help this of course).
The PL plantar-flexes and everts the foot. My theory is that I run in some stupid way where I am erroneously exercising the muscle, causing it to exhaust quickly. I don't know how good my running form is, but I strike the ground with the ball of my foot. I've tried different strides, but it seems everything outside my normal stride makes it hurt even worse.
Both legs get this, but the left leg gets in the worst (I'm right handed). Most of the pain is near the top, but it's not localized on the tendon.
Any ideas?
edit: After some googling I might have this:

Or I might just be doing this (Rotating the toes outward):
when I run, causing my PL to take the heat from running instead of my gastrocnemius.
