Hi Welcome to health care magic, All this symptoms of severe throat pain could be because of upper respiratory infection (pharyngitis, laryngitis, epiglotitis) or bronchitis. It is mostly due to viral infection like EB virus,adenovirus but some time could be bacterial or parasitic. In my advice,you may require higher antibiotics (quinolones or macrolides) to prevent super infection with antiinflammatory and other supportive treatment like bronchodilators if there is any breathing problem. Avoid cold water and carbonated drinks. Take steam inhalation and duolin nebulizers two or three time a day to get rid off cough. It would be advisable to see physician or ENT specialist with follow-up. Regards,
