Hello Ma'am. Very Good morning. I'm Dr.Yogesh Kr Sharma. As per your history given, May be you are suffering from common cold assosiated with upper respiratory tract infection, in view of such a high grade fever, requires a course of antibiotics for atleast initially for 3 days. Take two tablets of crocin 500 mg,  2 tablets each at once which means 1000 mg with cold sponging. Kindly come to practo chat for your treatment part. Regards.
