Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern...
As per your symptoms you are suffering from Viral Infection running nose,
cough and
sore throat is due to it. There might be a secondary bacterial infection along with viral infection.
Following remedies may be done
1.Salt Water Gargle- Mix 1 tsp of salt with warm water in a glass. Gargle for roughly 15-20 seconds and spit out. You can repeat this as needed for 2-3 days. Remember to spit the water rather swallowing it.
2.Take anti-inflammatory drugs like Ibuprofen/
acetaminophen it will reduce pain & swelling.
3.For congestion and stuffy nose you can take oral decongestant like Pseudoephadrine.
4.Drink plenty of water & Take rest.
You will start improving in 3 to 4 days..
Hope this information helps.
