I had a microbe in my lungs that caused me strong fever and fast heart beats?

I am a 29 yeara old male, I think I had a microbe in my lungs that caused me strong fever and fast heart beats, I consulted a doctor he gave me (derinox,maxilase,doliprane and tamiflu) i have been suffering for one week severe pain in my lungs when I cough or when I go up the stairs walk for a while. I still can feel the microbe in my lungs after one week causing me also short breath. I have also been drinking hot drinks, lemon, ginger, mint etc. i am just tired of this illness and need an effective medecine please.
