[|Human|] hello, i just notice a lump behind my 5month old right ear during bath time. he has no fever but was little cranky, i think it might be an ear infection. seems if you touch the lump he moves his head like it might hurts , please give me some information on this matter! thanks chuck
[|AI|]  Hello, I can understand your concern. The area behind ear contains lymph nodes. When ear gets infected, the lymph node in this area swells and causes pain. As it might be minor infection, the child has not developed fever yet, but he may develop if the infection is not treated at the right time. I would advise you to visit a pediatrician or an ENT specialist for clinical examination of the swelling behind ear and further investigations, if needed. If ear is infected, the child may need to start antibiotic course. I hope this information helps you. Thank you for choosing Chat Doctor. I wish your son feels better soon. Best,
