It seems there might be a typographical error in your question, as "artheritous" is not a recognized term in medical literature. If you meant "Arthritis," it refers to a group of disorders characterized by inflammation of the joints, leading to pain, swelling, and decreased mobility. Various types of arthritis exist, including osteoarthritis and rheumatoid arthritis, each having different causes and treatment approaches. If you meant something else, please clarify!
