Arthritis is painful inflamation and stiffening of the joints. There are three types of arthritis: osteoarthritis, rheumatoid arthritis, and psoriatic arthritis.

 

Osteoarthritis affects the weight-bearing joints such as hips, knees, feet, and spine. Cartilage in these joints deteriorate over time and the pain comes from these roughened areas rubbing together.

 

Rheumatoid arthritis is an autoimmune disease that attacks parts of the body, especially the joints. This can often lead to inflamation and potentially joint damage if not treated.

Individuals with psoriatic arthritis have inflammation of the skin (psoriasis) and joints. Fingers and toes can swell and fingernails are often pitted or discolored.
