There are many types of arthritis, but for now let's discuss about osteoarthritis.
Joints are where two bones meet. In any give joint (i.e. between two bones) there are cartilages, which are essentially soft bones that allow smoother movement with less impact.
Osteoarthritis (OA) is a condition where the cartilages are degenerated.
Now it is a common belief that degeneration of cartilages would cause pain. And yes sometimes it can, especially at the very severe end of the arthritis. However it is actually well-proven by most respected scientific researches that very often amount of pain people experience has little relationship with the actual severity of degeneration. And MANY, MANY people live out their lives, full lives, entirely unaware of arthritic joints that they would've discovered if they had X-rays.
There are complex reasons why and how that is so. But we can put it down to body's ability to adapt.
If you have arthritis, and unsure of what to do, we can help you. If you think "well nothing can reverse degeneration there is nothing else that can be done other than joint replacement", we would like you to have a chat with one of us, because that really doesn't have to be the case.
