Hi Dear . Welcome to HCM, Understanding your concern. As per your query you have severe cough and throat pain, well there can be many reasons for sore throat like tonsillitis due to bacterial or viral infection or in acid reflux . But in your case it seems to me that sore throat is probably because of viral infection , which usually go away by its own after completing the course. Vomiting along with cough is due to persistent infection of airways and sinuses. For now do warm saline gargles , take over the counter cough syrup and take ibuprofen or acetaminophen for pain and swelling. I would suggest you to consult ENT specialist gain for proper examination . Doctor may order test like throat swab test , viral culture test and blood test to confirm the diagnosis . Doctor may prescribe antiviral drug like acyclovir or antibacterial like amoxicillin depending upon the diagnosis and with anti inflammatory. Doctor may also recommend tonsillectomy. Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
