Massage -not the areas that hurt
Some experts think that arthritic conditions or pain conditions in general aggravate and flare up trigger points, and that one can get additional relief to arthritis symptoms trough self massage.
The idea is not to massage the area where it hurts, but to find pressure tender areas in your muscles near the actual pain area, and massage them instead.
For example, if your arthritis pain is in your knee joint, then you would find and massage tender points from your quadriceps muscles.
Exercises -lose it or use it
Not moving will only make matters worse in the long run, it's important to maintain as active lifestyle as possible.
Besides maintaining functionality, exercise can work as a natural pain medicine, because it helps to release endorphins, body's natural pain killers.
Just a half an hour long walk, can be all what's needed to release enough endorphins to make a difference.
Nutrition - dietary supplements may help
