<s>[INST] My 7 year old son was suffering from cough and cold since 3-4 days. Although now he has recovered, but his nose is paining and swollen and the swelling is increasing since last night. (He also has the habit of digging his nose). What could be the reason? [/INST] Hi Dear, Understanding your concern. As per your query you have symptoms of frequent cough and cold which is mainly because of respiratory tract infection, and it is due to poor immunity of body, and it is leading to increased susceptibility of getting infected. Need not worry about it. I would suggest you to visit ENT specialist once and get it examined and go for blood and sputum test to find exact cause of infection. Symptoms resembling flu and normally takes 3 days for viral fever to go. You should do warm saline gargles on daily basis and avoid cold beverages. You should take plenty of fluids and if it is bacterial infection start with proper course of antibiotics. Take proper rest without any discomfort. Hope your concern has been resolved.
