We have arthritis treatment options at both our Boise and Caldwell locations. There is over 100 different types of arthritis, but all relate to the informal way to refer to joint pain or joint disease. It is the most common among women and occurs more frequently as people get older. Arthritis can cause permanent joint changes. These changes may be visible, such as knobby finger joints, but often the damage can only be seen on X-ray. Some types of arthritis also affect the heart, eyes, lungs, kidneys and skin as well as the joints.
