The term "Arthritis" refers to more than 100 different types of diseases which all cause pain, stiffness, and inflammation in the joints of affected people. All arthritis conditions involve some form of joint pain or the other. However, the seriousness of the joint pain, the duration of the joint pain and degree of the joint pain vary from one type of arthritis to another. The two most prevalent types of arthritis include Osteoarthritis and Rheumatoid arthritis. Osteoarthritis is the most common form of arthritis, in which joint cartilage is destroyed. In other cases of Osteoarthritis, the patient experiences bony outgrowth, also known as bone spurs and also lose of cartilage particles. Osteoarthritis affects mostly aged people, from 55 years and older. That is why most people say it is an 'aged disease' of the joints. Osteoarthritis is mostly common in the hands, feet, spine, hips and knees of victims. In rheumatoid arthritis, the patient experiences white blood cells in the synovial membrane dividing, growing and multiplying. These produce inflammation of the joint capsule and synovial membrane, loss of space in the synovial cavity, pain and stiffness in the joint. If there is no arthritis relief and treatment, this may lead to cartilage destruction. Apart from these types of arthritis, another type of arthritis that commonly affects people is "Inflammatory Arthritis". This type of arthritis causes very severe inflammation in the joints and the tendons of the victims. This is mostly characterized by the swelling and inflammation of the synovial membrane - thereby causing severe pain and stiffness in the joints of the victims. Inflammatory arthritis makes the joint look red and warm when touched. Arthritis relief for victims is necessary to reduce the pain. Arthritis relief is therefore very important, especially in a country like the United States where Arthritis is the number one cause of physical disability. There are an estimated total number of 43 million Americans - 16 percent of the population, suffering from one form of arthritis or the other. It is not only adults who need arthritis relief, but also children. In the United States, about 300,000 children suffer from one type of arthritis related disease or another. Children, being very susceptible to pain, need arthritis relief and treatment more than ever before. Unlike adults who can endure joint pains to a great degree, children cannot and therefore need arthritis relief as soon as the problem starts.
