<s>[INST] My 11 month old has has chronic nasal congestion for 9 months with no relief from anything...antibiotics, humidifier, vapor rubs, hot steam, etc... wha can you suggest? Could it be mold in my home? Are there any natural ways to clear this congestion up? The pediatrician thinks the contant mucas is causing ear infections..HELP!!! [/INST] Thanks for consulting at Chat Doctor. Chronic nasal congestion in kids commonly occurs due to infections, allergies, irritants, enlarged adenoids etc. Chronic nasal congestion causes blockage of Eustachian tube which causes ear problems. Clear watery nasal discharge, rashes, sneezing may suggest some allergic cause. Sticky, yellowish nasal discharge, post nasal Chat Doctor. As you have already completed courses of antibiotics, I would suggest you avoid exposure to possible allergens, use nasal decongestants and oral antihistamines and arrange consultation with ENT specialist. He will do detailed clinical examination of nose, hypopharynx, throat and ear to determine the exact cause. </s>
