My 12 year old son keeps complaint about these two pea sized bumps on his neck. One is behind his neck near the hairline. The other is on the back of his neck at the base of his hairline. The bumps are hard and he complains of pain when I move them.
Hi, dear. I have gone through your question. I can understand your concern.  You may have posterior cervical lymph node enlargement due to some infection in scalp like pedicurists or others. You should consult your doctor and if needed to take a course of antibiotics.  If it doesn't respond to treatment then go for biopsy. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
