Hi Dear, Welcome to HCM. Understanding your concern. As per your query you have flu symptoms which are pointing towards upper respiratory tract infection leading to common cold, which can be caused by bacterial or viral infection. Need not to worry. I would suggest you to consult ENT specialist for proper examination. Doctor may order test like throat swab test and blood test to confirm the diagnosis and rule out causes. Doctor may prescribe antibacterial amoxicillin or anti viral acyclovir depending upon the diagnosis along with decongestants. You should take steam inhalation along with vaporizers. For now continue doing gargles and drink one spoon of honey mix with glass of lukewarm water. Avoid hot, sharp , spicy food. You should take diet rich in multivitamins to booster immunity of body. Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
