11. Cramp While Swimming

A: Ah!! I've got a cramp in my foot!

B: Stop swimming and roll onto your back!

A: It really hurts!

B: It will stop hurting if you rest a while.

A: Why did you tell me to roll on my back?

B: It's easier if you just float until the pain stops.

A: It hurts even if I don't move my foot!

B: At least your face is not in the water.

A: I think the cramp went away.

B: Can you move your foot now?

A: Yes; thanks for your quick thinking.

B: No problem. Let's get to the shallow water.
