on the end of my second toe,like in the ball of my foot area hurts pretty bad.its been hurting for a couple of weeks and it feels like there is a rock or something underneath it.at first i just thought it was where a piece of gravel or something poked me the wrong way, but its just not getting better at all.i can find a little sore spot, but only on the bottom of the toe and if i push on the top of my foot, i cant feel a sore spot.when i walk barefooted it hurts and when i curl up my toes or if i dorsiflex them when putting them up against the wall while doing a calf strech,it hurts as well. my trainer said it was mortons neuroma, but im thinking a possible stress fracture. any ideas?
