My 8 year old son had three knots behind his right ear on his skull that I noticed last night. Now he has one on the back of the right side of his skull, and two small in the center of his neck at the base of his skull. Do I need to take him to an emergency room? The ones behind the ear are tender to touch.
These lumps are called lymph nodes, which are found in neck, below the chin, below his jaws, in front and back of his ears and back of his head, they enlarge and become tender once there is an inflammatory process likely due to an infection , its usually proceeded by upper respiratory tract infection and sometimes small wounds and scratches.there is no need to worry unless they are growing in size, or have other lymph node enlargement like under the arm pits or at his groin. I hope this helps
