I borrowed the picture from someone else's foot problem that, when I read further, didn't seem to be what I'm going through.
Edit: (>_<) Scratch the picture, because I'm a new user I can't use them. Here's a link to the picture, but you'll have to disregard the OP's "It hurt's right in there somewhere."
A little background to paint the picture: I'm in the Corps and I LOVE to run... after about 2 months of uncomfortable pain in my right upper leg, near my femoral artery I went to medical. The day before, I'd gone on quite a long run. The following day it was nearly impossible for me to use my right leg... had to lift it into my car just to get in. Medical initially thought it was a hernia, whatever that is... but with some preeeeetty extensive examination of my down stairs mix-up they diagnosed me with a groin strain and pulled muscle near the artery. They put me on light duty for 2 weeks and told me not to run.
I hadn't really ran during that time :( but I did do some sloooow jogs after a week in... which brings me to my current problem. I think, because of my leg I was putting too much strain on my opposite foot and after today's jog that I did, now that I'm off of light duty... the pain in my left foot is excruciating. It looks slightly darkened around the area and hurts like a BLAM when I press down on it. Trying to figure out what it was on the internet, I had mistakenly rolled my fingers over the extensor digitorum longus tendons outlined in the picture to see if that was where the pain was. I'm pretty sure it's something to do with them... or the bone below it. IDK for certain... that's why I'm throwing this massive explanation out there to you guys.
Oh yes, and it also hurts during the run, when I bend my toes upward to press off from the ground... mainly on the inside, if I force my foot to land on the outside edge it takes away some of the pain. I can't NOT bend my foot to run, because I do the whole "natural" running scene thing, i.e. Vibram Five Fingers, Huarache sandals, etc. Except of course when I have to run in my combat boots. Landing on the heel is so bad for you. :-/
Hope you had time to read on this, and thanks very much to anyone who responds. -Semper Fi!
