Hi.. Myself Yashwanth N From India. I Was Fit N

Hi.. Myself Yashwanth N from India. I was fit n fine till last week. But from past 3 days high fever, feeling tiredness during day time. I went to consult a doctor. he suggested to eat paracetamol tab (forgot exact tablet name i think it is extacef 200(not 100% sure)). From the time i have taken that tablet. Not able to sleep at night. Feels like difficult in breath which in turn causes cough. Can any1 tell me whats the actual issue with me?
