Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain it seems that you are suffering from upper respiratory tract infection also known as Common Cold or can be due to Influenza or Flu leading to the symptoms of high fever,sore throat,chest pain,and cough.. Consult an Otolaryngologist and get evaluated and a thorough clinical evaluation and investigations like throat swab culture, sputum culture and blood test can help in diagnosis.. You can be advised antibiotics like Augmentin, a combination of Ibuprofen and Tylenol, anti allergics like Levocetrizine, decongestants like Phenylephrine, Mucolytics like Bromohexine.. Warm saline gargles, steam inhalation and using a humidifier in your room can help.. You can also chew Vitamin C pellet as it will help in improving immunity.. Take a soft diet with ample of fluids.. Avoid spicy and chilled foods.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
