As per your query you have symptoms of  flu & high fever. Well there can be many reasons for symptoms you mention in query , but in your case it seems to me that the symptoms are due to viral infection or viral pharyngitis. It is due to poor and compromised immunity of body and increased susceptibility of getting infected. Need not to worry. I would suggest you to do warm saline gargles several times a day , drink plenty of water to stay hydrated and consult pulmonologist for proper examination. Doctor may order throat swab test and blood test . Usually it will go away by its own in few days , but doctor may prescribe antiviral like acyclovir , anti inflammatory along with drug like sucralfate to heal throat lining in severe cases . Hope your concern has been resolved.Get Well Soon.Best Wishes,Dr. Harry Maheshwari </s>
