Yesterday I went out for sometime and the weather was too hot. Although I didn't felt anything at that time but from yesterday afternoon i was having burning and lump type pain in my throat and headache and also mild fever. I took paracetamol calpop 500mg and cefkem 200 in evening. And then montek LC at night after consulting a doctor in my family. But then I get high fever (102.3) in morning today. Then after light breakfast I took paracetamol again and Monocef 200, but my temperature raised to 103.6 afrer sometime and then after taking a meal it came down to 101.7 , and headache continued in low and high intensity, then I again took half tab of paracetamol , and Zathrin 250 after lunch. But my temperature is still high and headache is persistent. What should I do ? Please advise.
