Rheumatoid arthritis is one of a group of conditions called inflammatory arthritis, that also includes psoriatic arthritis, ankylosing spondylitis and lupus.

A physiotherapist will advise you about any exercises you can do to ease symptoms and strengthen muscles.
If your joints are badly damaged, you may need surgery to restore mobility. This can include operations to reduce inflammation or pressure on nerves or tendons, a hip replacement, or a joint replacement in severe cases.
