Why do we as humans cry out when in pain?

Today I sprained my ankle. It was a very painful experience and was screaming. Ive hurt myself many times before, but this was one of the first times I ever really screamed out in agony. Was curious as to why we do this?

Many species vocalize pain somehow. Coming from an adult, it's a warning for everyone else in the group that something nasty is going on, and they should be on the alert. Coming from a child, it's a cry for help.
