Rheumatoid Arthritis is a condition that affects a person’s joints. Joints are like the hinges on a door, allowing us to move and bend our bodies. Sometimes, our bodies can get confused and think that our joints are not friends, but enemies. This causes the joints to become swollen, red, and painful. It can be hard for people with Rheumatoid Arthritis to do things they enjoy, like playing games or going outside. But with the help of doctors, they can find ways to make things better and feel less pain.
