Hello,
As a physician and as per my knowledge, the sudden onset of symptoms of any one of the fever, feverishness, nausea, Malaise and any one of the cough, cold or
shortness of breath, it's known as
influenza like illness.
So, you have nasal discharge along with now feeling fever and intense cough and you have
severe body ache, weakness then I will suggest you to go for flu test.
Till now, you can take tablet Dolo, tablet Okacet cold, and tablet
Ranitidine. You can take steam inhalation and
Betadine gargle twice a day. Keep yourself well hydrated, maintain your proper hygiene and keep yourself warm also.
I will suggest you to review here with detailed history or consult with physician with reports.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Shyam B. Kale
