There are pain syndromes like fibromyalgia and arthritis-related disorders, such as systemic lupus erythematosus, that involve every part of the body. There are relatively mild forms of tendinitis (as in 'tennis elbow') and bursitis to crippling systemic forms, such as rheumatoid arthritis. There are forms of the disease, such as gout, which almost nobody connects with arthritis, and there are other conditions - like osteoarthritis, the misnamed 'wear and tear' arthritis - that a good many people think is the only form of the disease. How do you know if you have arthritis? While symptoms and severity vary from person to person, the most common symptoms are: pain, swelling, stiffness, tenderness, redness and warmth. Osteoarthritis is characterized by progressive stiffness without swelling, chills or fever. Sometimes natural herbal remedies are used to treat rheumatoid arthritis which is the painful swelling, inflammation and stiffness in the fingers, arms, legs and wrists, which are prevalent on both sides of the body and are usually worse in the morning. Children with on-off fever, loss of appetite, weight loss and a blotchy rash on the arms and legs might have juvenile rheumatoid arthritis. You should call the doctor if symptoms appear suddenly, or if they are accompanied by a fever or rash.
