FEVER

Today, I am having fever. It's so bad. My whole body was pain and headache. I use to get Medical leave from doctor today. He gave me antibiotics . But I heard before if we took so much antibiotics, our body will cannot accept any medication anymore in the future. Is it true?
I dont know. I did not took that antibiotics yet but i took paracetamol just now. And I slept for 4 hours. Now I feel quite well. It maybe because of the bad hazard outside.
