Arthritis & Rheumatology

Many people start to feel pain and stiffness in their bodies over time. Sometimes their hands or knees or shoulders get sore and are hard to move and may become swollen. These people may have arthritis. Arthritis may be caused by inflammation of the tissue lining the joints. Some signs of inflammation include redness, heat, pain, and swelling.

What is Arthritis?

There are over 100 disorders that typically affect joints, tendons, ligaments, bones, and muscles and are termed arthritis and rheumatic diseases. Some of these may also involve internal organs.
