Hi there.
I have a few queries to you.
Do you get recurrent attacks of cold?
Do you have any allergy? Dust Allergy, drug Allergy, food allergy?
Do you have recurrent sneezing?
Are you on any medications?
Your symptoms are suggestive of a sinus infection.
Since you've mentioned about fever or thick nasal secretions, it's more in favour of a bacterial infection for which you don't require antibiotics.
Next Steps
Try taking a
vitamin c supplement once a day.
Avoid cold foods.
Start doing breathing exercises.
Do steam inhalation twice a day for 5 min in each session. Plain water is sufficient.
Also do salt water gargling thrice daily.
Get sun exposure for 30 minutes a day.
All for the next 5-7 days.
Health Tips
Don't sneeze too much.
Don't squeeze out your nose. it can aggravate Allergy
