Today i was walking in my kitchen then i got a very very small peice of glass in my foot. I felt a small sting after i stepped on it. But then i checked my foot there was just a little bleeding, i decided to take it out with tweezers after i started to pick through the skin i realized i couldnt see it even with the strongest light next to my foot. Its not painful at all just a little sting, that goes off and on the problem is i cannot see it, and do u think that this small peice of glass can cause an infection
