Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern...
As per your complain and presentation of symptoms you are suffering from Viral
Throat Infection and the runny/stuffy nose and yellow roof of the mouth is due to it only..
Nothing to worry you can take antibiotics like
Azithromycin or
Augmentin as there might be a secondary bacterial infection along with viral infection..
Take anti-inflammatory painkiller like
Ibuprofen.
For congestion and stuffy nose you can take oral decongestant like Pseudoephadrine [Sudafed].
Saline nasal sprays can help in thinning the thick mucous in nose and ease draining and clearing congestion.
Do warm saline gargles.
Do steam inhalations.
Avoid spicy and hard foods.
Avoid chilled foods and liquids.
Drink plenty of water..
Take ample of rest..
You will start improving in 3 to 4 days..
Hope this information helps..
Thanks and regards..
Dr.Honey Nandwani Arora.
