Glass in skin, how to remove, is this harmful??

Last night a bottle of glass fell on the floor and exploded a little bit because it had some leftover juice inside, which rotted. so it created gas, hence the small explosion. I got a few pieces of glass in my leg which I could see and remove. But i think i still have some small ones cuz it has been itching all day. Could this become an emergency or is it silly? my mom says it could get into my blood… Is this true?
