There are many types of arthritis, but osteoarthritis is the most common type. The cushioning surface on the bones wears away, and bone rubs against bone. The joints can lose strength, and joint pain is often chronic. With inflammatory arthritis, the immune system goes awry. It attacks the joints with inflammation. This can cause joint erosion and joint pain. Infectious arthritis occurs when a virus or bacteria enters the joint. Even though antibiotics may end the infection, arthritis can become chronic. Metabolic arthritis is due to too much uric acid in the body. It can build up and cause chronic joint pain.
