The Centers for Disease Control and Prevention (CDC) issued a new report on the rise of arthritis and joint pain in the United States. Appropriately enough, we've decided to blog about it on World Arthritis Day, October 12. According to the CDC report, approximately 50 million people have some type of arthritis. Rheumatoid arthritis, lupus, gout, osteoarthritis are among the many types of the disease mentioned within the report.
