Hi, may I answer your health queries right now ?  Please type your query here...   I was just putting my 18 month old down for his nap and noticed that he has a huge lump on the left side of his neck, under his ear area.  He had strep and a ear infection last tues. started antibiotic, he is still taking the meds, but today has a horrible stuffy and runny nose and cough.  Should I have him seen for the lump?
Welcome to Chat Doctor. The most possible cause of the lump is enlarged lymph node. Lymph nodes are enlarged after an infection / inflammatory process. Let the treatment gets over and see for reduction in size, is resolved after 1- 2 week of treatment well and good, if not - then needs to examine and scanned for any congenital abnormalities. For which you have to see pediatrician. Hope it helps you. Wish you a good health. Anything to ask ? Do not hesitate. Thank you.
