I have been training for my first marathon for 4 months now, and I have been an avid fan of Vibram 5 Fingers since for at least 3 months, logging around 250 miles in them. I've had no uncommon problems until recently.
I am experiencing a sharp pain in what I believe is my extensor hallucis longus tendon as I dorsiflex after a footstrike with my left foot. The pain is not in my foot--it is 4 inches above my foot in my shin, not right at the tibia, but less than an inch toward the outside. As I dorsiflex my foot, I feel the once dull, now increasingly sharp pain. After today's long run, I feel the pain even while walking.
This happened after running 16 and then 18 miles on consecutive Saturdays, and after today's 8.5 miler. It initially began this past week after my 18 miler. It may be my body's way of telling me to take a break, but I'm wondering if anyone else is familiar with this injury, and what they did to treat it. I'm going to do the obvious (RICE method, ibuprofen, specific stretches, birdseed rehab). Is this a common injury among the VFF community?
