What is this bubble like thing on my foot?

I went skating last night and the side of my foot hurt like usually when I skate for a few hours. But today my foot still hurt and I looked at it and there is this air bubble like thing on my foot. It's kinda like bubble wrap that's made out of skin. I don't know if I should like tell my dad about it and have him take me to the doctors or something but it's really freaky. And know since I noticed it im not gonna forget about it until it goes away. Can you help me Cuz it hurts when I touch it so I don't think I should pop it but I'm not a doctor and if you know what this is can you give me the name two so I can look it up on my own? Please help me,
Thank you! :)

THAT's called a "Blister." And we get Them when we're putting TOO much "pressure"- on a given "spot" on our Bodies ( usually on Our Hands or feet ). Just leave it ALONE, and it will eventually ( after 3 or 4 Days ) go down, flatten out & peel off- in about 10 days or So . :)
