[|Human|] My son is 1 year old. He has been having chest fullness for the last 1 month , treatment has been taken ( homeopathy) but did not subside. Last week I took to a pediatrician , he prescribe antibiotic n some expectorant sup. But still chest fullness running nose still present. Xray has been done n shows left lung infiltrate. But when he sleep at night no sound is heard on breathing, he sleep peacefully, eat well n chest fullness is more when he is active
[|AI|]  Thanks for consulting at Chat Doctor. A lung infiltrate is a substance denser than air, such as pus, blood, or protein, which lingers within the parenchymal of the lungs. Lung infiltrates are associated with infections like pneumonia, allergic bronchitis, eosinophilic lung disease, interstitial lung disease etc. In your case chest congestion, runny nose suggest its probably due to allergic cause. Episodes of cough, chest congestion, runny nose may occur due to exposure to an allergen. You will need to identify what is triggering such episodes. It may be allergens like pollen, dust, mite etc., Sometimes chemicals like perfumes, mosquito repellents etc. Adequate treatment may not be as effective if exposure to allergens is continued. Ask your doctor for adding broncholdiator-steroid nebulization, antihistamines etc.
