Cough, fever and chills. Pls advice.

I had a fever on 28 Sept, Wednesday at night for the first time 102 degrees. I had lot of chills also. I saw the doctor on 29th Sept, Thursday and he told me that it's common cold. Doctor recommended 2 paracetamol every 8 hours for 5 days & 1 ibuprofen every 8 hours for 3 days. Even after taking medicines, the fever and chills continued until 2nd Oct. It lowered the temperature with the effect of paracetamol but only for 5 hours. Later the fever returns again. I had no fever between 3rd Oct to 5th Oct. 6th Oct, Thursday begins again cough and fever and chills. I went to the doctor and he prescribed amoxicillin 500mg every 8 hours for 7 days. Inhaler every 6 hours for 7 days with 2 puff. Even the fever continues until 9th Oct, Sunday morning. I am also having a bad dry cough. There is fever with much chills. And there is lot of perspiration after the fever. Coughing continues till today and I feel obstructed. I'm taking 1 paracetamol every 8 hours and Desloratadine at night. Pls advice.
