I have increased my walking in the last 3 weeks (2 miles a day) and am riding my bike. I have started having pain on the side of the ball of my right foot. I can touch all around with no pain but when I touch directly on the side of the ball, I have serous pain. It hurts when I move my big toe, but not as much as direct pressure on the side. Today I also had pain going up the top of my foot, when wearing shoes, but no when I take them off. No swelling is evident. There has been no trauma to the foot, just increased walking time..
