Hi My son is 18 months old, a happy little boy. However he has an enlarged pre-auricular node on the right side of his face, close to his ear. It has been there nearly 8 weeks, and it is about 0.7 cm. It changes colour from purple to red and its movable, but very solid. If I touch it, it does not hurting him. I have been to the GP 5 times in the last 8 weeks, and I have been told 5 times, it is only a virus. He hasnt got a cold or a sore throat. But the node has grown in the last 8 weeks. Please any idea, what it is? I am very concerned.
