Osteoarthritis

In some people, the condition can damage a wide variety of body systems, including the skin, eyes, lungs, heart and blood vessels.An autoimmune disorder, rheumatoid arthritis occurs when your immune system mistakenly attacks your own body's tissues.

Tenderness. Your joint might feel tender when you apply light pressure to or near it.
Loss of flexibility. You might not be able to move your joint through its full range of motion.
Grating sensation. You might feel a grating sensation when you use the joint, and you might hear popping or crackling.
Bone spurs. These extra bits of bone, which feel like hard lumps, can form around the affected joint.
Swelling. This might be caused by soft tissue inflammation around the joint.
