It all started when i was in a school to guide students for their camps. I got an itchy spot on my feet. I though it was a normal mosquito bite so i scratched it like i usually would. Wore my shoe and to the outdoors to play some games with the kids and when i removed my shoe, it suddenly become a water bump. It was weird as i had never encounter this before. I don't know whether it was cause by the socks that im wearing or the shoes. Any ideas? Few days later, it pop-ed and now the skin looked really horrible like as if i have a big flat mole on my feet. Thinking that it has pop-ed, i thought of peeling the outer layer but i can't. There's no hole to at least peel it. What is this weird thing on my feet? Should i see a skin doctor?
