What Could Dry Spots On Toe Suggest ?

Hi, I had a small dried point on my toe. It used to hurt when it got pressed on the ground. as days passed by, more and more of such tiny dry and thick points started developing and their size Increased but not much. It pains a bit wile walking because of It. I was wondering if I could know a bit more about this before approaching a doctor. Could some one help me plase?
