My 3yo son has a lump on the right side of his face in front of his ear. It is about the size of a kidney bean and moves quick a lot. We lightly banged heads this morning in this place and he burst into tears so I know it is painful. His right eye is also red. He has a runny nose and cough plus his eczema has also flared up. He has not been sleeping well and I'm wondering it the lump hurts when he sleeps on his right side. We went to the doctor yesterday (I diddn't know about the lump then) and he checked his ears and chest and he was fine. Is it just a lymph node that has swollen up because of his cold or could it be something else.
