| What
Causes Osteoarthritis? |
| |
| The cause of osteoarthritis is not fully known.
The cartilage can be damaged prematurely by the abnormal stress put
on the joint due to previous injury, obesity and abnormal joint shape.
Sometimes, the cause is simply wear-and-tear from old age. |
| |
| |
| Signs and symptoms |
| |
| You might have osteoarthritis if you experience the following. |
| |
| |
| Pain and stiffness |
| |
|
|
The pain in the joint is worse
during or after use. At a late stage of the disease, you may
have pain even at rest. Your joint may feel stiff and painful
to move after a long period of rest and keeping still, as when
first getting out of bed. You may also feel some discomfort
from changes in weather. A painful and stiff joint can stop
you from doing simple things like walking or just having a good
sleep. |
|
| |
| |
| Swelling |
| |
|
|
Usually, the swelling occurs after activity. The
joint looks swollen and the overlying skin feels warm. |
|
| |
| |
| Bony lumps |
| |
|
|
The prominent lumps on the joint
come from poor cartilage repair that leads to growth of new
bone on existing bone. |
