Initially, it compromises the smooth cartilage lining of the joint, making movement more difficult and leading to pain and stiffness.
It mainly affects joints in the hands, knees, spine and hips.
The second most common type of arthritis is rheumatoid arthritis, which is when the body’s immune system targets affected joints, causing pain and swelling.
Symptoms of arthritis will depend on what type you have, but can include:
- Joint pain, tenderness and stiffness
- Inflammation in and around the joints
- Restricted movement of the joints
- Warm red skin over the affected joint
- Weakness and muscle wasting.
