Today, I noticed a splinter, or what I thought was a splinter, sticking out of my face . I went to pull it out, and it was a hard, white stick. It won t bend or break. It s not sticky either. This is the third time it has happened. Twice has been in the same spot on my face. Another time was in my right shoulder . It s not wood, plastic, or metal. All three times, the splinter has been the same length, color, and diameter. What is this?
