How are high fever and infection linked to each other?

Hello doctor,

I had gone to a wedding. After I came back, my head was burning, but I did not pay attention. But the next morning, it was 101 degrees Celsius. I took Crocin and was fine for three hours, but my eyes were burning again, and I was feeling cold.

So I went to sleep. Then, when I got up, it was 102 degrees Celsius. Again, I took Crocin and was fine till night. But the next day, the morning temperature was 104 degrees Celsius.

My eyes were burning. I had body aches and pain on the right side of my head. I took Dolo, and it started working after two to three hours and was fine for almost the whole day. In the evening, I felt slightly feverish, but it was fine.

Now, when I get up in the morning, again, the temperature is high. The fever is repeating, it seems. I suffer from bronchitis, so whenever I have a fever, I often suffer from congestion in the chest, heavy cough, and runny nose, but this time I do not have any symptoms but a very mild dry nose. I have my interviews coming up.

Kindly help.
