I have a blister on my big toe, should i pop it?

I went to the warped tour and walked around all day. I was wearing Vans shoes so that's probably what caused it to form. It's on my big toe. It's about the size of an M&M. It's squishy and it doesn't hurt. Looks a little yellowish and clear. I just keep a band aid on it. I don't know if i should pop it or not.
