Hello,
      Welcome to HCM and thanks for asking your question. I can understand your concern.      
      I want to tell you that most probably you are suffering from simple 
flu and need not to worry much about it. I would advise you to work up few things like blood CBC, 
Creatinine, blood sugar and chest x-ray.
      If i were your treating doctor, i would have suggested you to take anti histaminic drug and anti inflammatory drug. No antibiotics are required at this stage as per my opinion. Take few precautions like have a 
steam bath, avoid going in dusty and in public places, take a break from your job...If you will have symptoms like difficulty in breathing, high grade 
fever, 
palpitation, then you should immediately contact a physician for further work up.
      Mostly you will be relieved from flu within a week or so, so don't take tension. Hope this answers your question and let me know directly if you have any further relevant queries, i will be happy to guide you in right direction.
