(WTVM) - According to the Arthritis Foundation, arthritis is the leading cause of disability in the United States.
Dr. Paula Walker King explains that symptoms of arthritis include joint swelling, stiffness, joint pain, and a decreased range of motion in one or more joints.
Physical activity decreases pain and increases joint function. Other treatment to manage the condition includes anti-inflammatory medication and aquatic therapy.
Arthritis can be diagnosed by laboratory tests and physical exams.
