[|Human|] hi,my 5 years old son has a swollen lymph node on his neck and another one -2cm in size- found on the size of his chest with an x-ray last week. now he is going for an abdominal ultrasound to find out if there is any other in the areas. he has diagnosed to have a dust mite allergy over a year ago and since then he is on Avamys. it seems to help but he still gets runny nose time to time and takes his fingers to his nostrils quiet often. lately we even noticed he made his nose bleeding. Naturally, I want to hear that his nodes are related to his allergy hence rhinitis. Any ideas? Thank you in advance
[|AI|]  Common causes of cervical lymph node enlargement in a child are infections in pharynx, tonsils etc.However, other serious conditions like lymphoma, tuberculosis, acidosis etc. also cause significant lymph node enlargement. As your child is known case of allergic rhinitis, probably enlargement is due to infection. Your doctor may advise investigations like USG, lymph node aspiration cytology, blood investigations to ascertain exact cause.
