Arthritis describes a range of conditions affecting muscles, bones, joints and connective tissue in various parts of the body. Generally speaking, it causes joints to stiffen and become inflamed; sometimes after injury, or because of a virus. Genetics play a part too. There are around 200 different forms of arthritis, ranging from osteoarthritis - essentially wear and tear to the joint and the most common type - to auto immune forms, like rheumatoid arthritis, when the body attacks its own tissues by mistake.

If you're looking for answers, this essential guide will provide them; and show that by staying positive, keeping mobile and getting the right treatment, you can manage your condition effectively - and get on with the rest of your life.
