Arthritis is a common condition that causes pain and inflammation in a joint. According to the NHS government statistics, there are around 10 million people affected by arthritis in the UK. Unlike popular belief that it affects only the elderly, arthiritis actually affects people of all ages, including children. Two common types of arthritis are osteoarthritis and rheumatoid arthritis. In osteoarthritis, the cartilage (connective tissue) between the bones gradually erodes, causing bone in the joints to rub together while in Rheumatoid osteoarthritis the body’s immune system targets affects the joints, leading to pain and swelling.
