From Past 3 days I have body pain and weakness. I started with tickling in my throat and in 1 day had no issues with the throat.. I do not have fever till now and body ache is also reducing but I feel my 1 nose blocked and a very little coughing which is just a feeling of coughing.. .. I ve visited the doctor and he has prescribed me solphure-C , Azithromycin, fenalin SP and feloz 20. He said it's seasonal flu.. should I be worried??
