i see that someone asked almost the same question; few weeks ago i noticed the left corner of my big toe seemed a little lighter or whiter than rest of the skin ( almost like wen u wear a bandaid for a long time and wet your hands- wen u remove bandaid the skin is lighter. so the day after, it seemed like a little blister, no pain( i had never hurt myself there at all) i cleaned w alchohol and squueezed the corner and some yellowish sticky oozy liquid came out. since then, the corner skin is very crusty and dry and idont know why this happened out of nowhere
