Pain sends a certain signal to the brain. Other sensations also send a signal. When you have pain signals going to to brain, you can dilute these signals with other signals. Now, instead of there just being pain signals, there are other signals as well, as your brain isn't interpreting the pain signals alone, but a variety of signals including pain, so the pain signals aren't the only thing being focused on by the receptors, and the pain isn't as bad.
