Hi, may I answer your health queries right now ?  Please type your query here... Hello. My almost three yr old sons has swelling on the left side of his face.  It looks like his lip and under his chin is swollen maybe his lymph node?  Should I take him to the dr?
Hello, I can understand your concern. Has he suffered any trauma recently in the chin area? The area you have described swells when left sided lower front teeth are infected. It can be due to trauma to the teeth or involvement of teeth by decay that oozes pus near root can cause swelling of the lower lip and area below chin. Alternatively, in case of absence of infection, he might be suffering from allergic reaction to some food or environmental substance. I would advise you to visit a dentist for diagnosis of infection in the lower front teeth. Further treatment can be advised after the confirmed diagnosis for the swelling. I hope this information helps you. Thank you for choosing Chat Doctor. I wish your son feels better soon. Best,
