Big toe pain

I'm looking for suggestions for the pain I'm feeling in my big toe.  It basically runs along the top of my foot from the joint in my toe straight back to my ankle.  That muscle? is sore to the touch and it hurts to walk or run.  This does not happen consistently, but usually is a problem 3-4 miles into a run.  Maybe I need to do some kind of stretching of foot muscles???

I'll take any suggestions.  Thanks
