I started experiencing pain in my foot about 3 weeks ago. I figured that my old shoes were just too worn out, but I was planning on getting new ones so I just cut back my mileage a bit in hopes that nothing would get worse. Got my new shoes, woot! But the foot pain got much worse :(
Luckily my landlord/neighbor is a podiatrist. So I went to see him and he says my facia, or whatever the name of the tendon in my arch is called ;), was hurt. So he taped up my foot and said no running, waah. I am going on vacation (Vegas baby!) so I wont be able to see the dr again until friday, the 10th.
I'm pretty bummed out, but hope that a week or two off of running will take care of everything and I can jump back in to training and still get to run the planned marathon. I started taking a spinning class in hopes of keeping up my aerobic capacity.
In other words, blah blah blah, don't run and try not to go crazy in the meantime.
