question: I found 2 bumps behind the ear near the hair line on both side of my 7 week old grandaughter. I am very concerned she appears very healthy growing and doing great. I hated to say anything to my daughter as I hated for her to get so upset before her next Dr. appt. on the 17th. They are about the size of a bb and do move with the skin, and appears that it does not hurt. Please hope you can give me some good news. She is our main life right now and I pray it is nothing. On the right side about 1/2 inch below the one at the hair line is another tiny one on the neck. I feel it is lump knobs but why would this happen?
