World Arthritis Day: All the symptoms you need to watch out for

Arthritis is an autoimmune disease that affects the joints, causing them to inflame and swell.

According to the Arthritis Foundation, about 1.5 million Americans are struggling with arthritis.

Arthritis symptoms vary from person to person depending on the severity of their condition.

Morning joint stiffness is one of the major indicators of arthritis.

Once the disease is active, affected joints become swollen, painful and even feel warm to the touch.

Chronic inflammation due to arthritis can result in damage to bone, cartilage, tendons and ligaments.

Non-joint symptoms of arthritis include fatigue, fever, loss of appetite and unintentional weight loss.

Doctors usually diagnose arthritis using the patient's medical history, physical examination, X-rays and blood tests.
