<s>[INST] My 3 year old son is having a fever for last 3 days yesterday the doc gave a vaccination for fever to reduce also for cough to come down ... also suffering from sever chest conjestion and cough now he has started passing frothy motion is it because of the mucus or something more serious [/INST] Hi Dear,Understanding your concern. As per your query your child have fever and cough which is due to chest infection due to poor immunity of child. I would suggest you to consult pediatrician once for proper examination as infection has already spread. You should get throat swab test and complete blood profile to find out extent of infection. You should start with antibiotic such as augmentin along with decongestants and anti inflammatory such as Levocetirizine. Take diet rich in multivitamins. Maxtra and levolin syrup is a safe combination for child. For now do warm saline gargles. Take steam inhalation. Take proper rest and keep yourself hydrated. Maintain hygiene. Hope your concern has been resolved.Get Well Soon.Best Wishes,Dr. Harry Maheshwari </s>
