Vasculitis (Kawasaki) is inflammation of the blood vessels due to changes in the blood vessel walls, such as thickening, weakening, narrowing or scarring, which leads to restricted blood flow and damage to organs and tissues. There are many types of vasculitis, most of which are rare. The condition can be acute or chronic, so depending on the type, it may improve without treatment.

Heart pain is a symptom that is not only common in adults but also in children. It is a warning sign that the heart is having certain damage. Therefore, when parents see their children having heart pain, they need to take their children to a medical facility for timely diagnosis and treatment.
