Throat Pain and Chest burning irritation

Hi Doctor, I am a final year college student staying in Hostel, 3 days ago I have severe pain while swallowing. I used to take warm water with salt to treat this problem. Pain is reduced. But after 1 day I got severe throat pain along with fever and headache, I cannot able to drink a water itself. I consulted a doctor, he recommends me to take CEPODEM200 TABLETS MORNING AND NIGHT. It actually helps me with swallowing problem. But while awaking in the morning, I have a same severe throat pain along with chest burning irritation with vomiting which is rectified along a day and continues in every morning. Kindly help me with some MEDICATIONS AND FOODS for reducing this problem. My final year exams are on the way. Kindly I don't need the worst pain scenario in morning.
