Hi doctors. My son 1.5 years old weight 10.7 kg having swallown 3  nodes just behind ear and 1 on neck . it is for about 20-25 days. In starting it was very small but now large and 3 behind ears and 1 on neck. No pain no redness .   I tested for tuberculosis skin test which was negative and done chest xray and blood test to confirm. So I m attaching x ray and blood test for confirmation. Maintaux test show negative. So what are the reasons for these swallown nodes. Please explain . and one more thing .he pulls his ear more times and sometime slaps on ear. And I can see white dry thing inside both ears. So these nodes can be due to ear infection. What to do.
