Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
It seems that you are suffering from upper
respiratory tract infection and the symptoms of
sore throat, fever, phlegm and diarrhea is due to it.
As it is a viral infection, it will resolve once the virus will complete its cycle in human body.
As of now, in order to relieve the symptoms, you can start with supportive treatment like:
-Gargle with a warm saline solution that is by mixing 1 teaspoon salt in a glass of water and warm it to make a luke warm solution.
-Take a combination of decongestant like
Phenylephrine, mucolytic like Ambroxol and anti allergic levocetrizine and another combination of
Acetaminophen and Ibuprofen.
-Take cough expectorant containing Gueifenesin and cough suppressant containing
Dextromethorphan.
-Chew a Vitamin C pellet daily.
-Do steam inhalations.
-Avoid spicy and chilled foods.
-Sip on warm water throughout the day.
-Do warm compresses over chest.
-For diarrhea, you can take Loperamide.
Hopefully the symptoms will resolve within a week and if it worsen then consult a General Physician and get evaluated.
Hope I have answered your query. Let me know if I can assist you further.

Dr. Honey Arora
