Diverting attention can relieve the pain. I usually lie in bed to sleep when it is very painful. When I fall asleep, I can't feel it anymore. 
I guess diverting the attention to things that can produce feeling that is opposite of the pain.
I usually prefer to let my pain stay, then try multiple things to see what works for me consistently and very effectively.
As a religious person, diverting attention to deep prayers, having enough faith, deeply focusing on GOD's Words work for me always. .. But sometimes i feel I don't have to keep bothering GOD for thesame pains/illness I most likely caused myself by always allowing unhealthy things like bad foods/air into my body, probably due to the environment I live in, and I'm unlikely to stop living in soon ... i then decide to try multiple natural treatments like:
1. drinking blended fruits/vegs,
2. drinking warm water,
3. drinking tea/herbs,
4. doing nice things to people (which kind of increase happiness/joy) , etc.
I think doing 1 to 4 (esp 4) works consistently for me... but tend to work gradually rather than immediately. The faith-based ones work quickly/immediately.
