I had one of those on my eye. It was like a little whitehead, but level with the skin, now raised above it. I used a pin & poked the skin & it came right out. I WOULD NOT recommend doing this tho. It is VERY dangerous and I have not a clue as to what I was thinking when I did it! It was VERY VERY stupid on my part! How long have you had it? I wonder if they would turn into a pimple and go away or possibly go away on their own?
Good luck & keep us posted,
