Fever since Monday. My bub like that!

Hello, my daughter is having fever since Monday afternoon and hasn't reduced..also she had ear pain since long time and yesterday consulted ENT said it's Bilateral dysfunction and suggested some nasal spray and syrup but point is she is having fever and it's not reducing every 6 hours fever is coming and I am giving her Calpol 250 also she complaining of little body pain and having nausea. When I see her throat I can see 2 bubble like in her throat. About ear pain it was last time it started while she catched cold while she flew for the first time. It subsided but in middle too she used to tell she has pain while she burps. So went for consulting now as it continued 2 days back too. Please guide me what should I do. As she is not sleeping well, not eating well an as a Mom I can't see my bub like that
