I took my six year old daughter to the doc about a month ago because of a lump on the left side of her head near her ear.  The doc prescribed antibiotics--which my daughter completed, and the lump is still there.  Because the lump was still present, we did blood work, but nothing was found.  Six weeks later, my daughter still has the lump on the left side of her head, and now a smaller lump has appeared on the right side of her head.
Hi I am Chat Doctor and I will help you with your problem have gone through your question. Needs answer to some questions to reach diagnosis- a swelling is single or there is group of swellings?- any history of fever, night sweats or weight loss?- any history of throat infection?- skin changes over the lump?Anyhow, with available information it appears to be lymph node enlargement of post auricular group. It Chat Doctor.  If it does not respond to antibiotics it might be some other pathology. You need to see a general surgeon, who might carry out biopsy of the lump and send it to histopathology to get a definitive diagnosis. I hope my answer will help you. Do rate it if you like it.
