What does arthritis look like?

After reading my blog I'm sure you all know by now that people of all ages are affected by arthritis. But some of you may be wondering what exactly arthritis looks like. Arthritis is known as an invisible illness which means you can't tell that someone has it just by looking at them. This is true for most people, but for some the joints can become incredibly swollen and disfigured, especially during a flare.

Above are pictures of joints disfigured from arthritis. These are not my pictures, they were taken from google.com.
