I just stepped on a long piece of glass from an iPhone 5?

Is this bad? It went in sorta deep but I got it out. I was reading a thread that the chemicals on the glue are toxic do I need to go to a doctor or? Some one help

You're fine if your tetanus shots are up to date. You might want to see a doctor if it was a deep cut anyway, though. The wound needs to be closed so no other dirt can get in and infect it.
