On Friday I completed a 16k sponsored walk with the school I work at, and then, on Sunday, I ran a tempo 5k with no apparent after effects. This morning, when I got up, I immediately noticed a tender spot on the sole of my foot - feels a bit like I've stepped on a sharp stone as if it's bruised.
Having googled my symptom, it sounds very much like pf. Has anyone else suffered with this and if so, please tell me it clears up quickly! X
