For some strange reason people rarely wear a "Help Wanted" sign when they need help. Sometimes it seems like the more a person actually needs help, the less likely he is to ask.
That's one of the reasons why I'm a big fan of random acts of kindness.
Just... doing small but meaningful things for other people, whether you know them or not. Giving somebody a ride home in the rain, cleaning litter when you see it, opening a door for someone or getting a cup of coffee. Maybe just sharing a warm smile with someone who may need it. If I have a bad pain day, I try to get out of my self by thinking about what I can do for others. Maybe I can help others by sharing my experience? If I'm in shape to cook, can I prepare a couple portions extra and bring some to a friend who is going through a rough time?
Anything that makes me feel better also reduces my experience of pain.
