HI, thanks for using healthcare magicNasal congestion
can be related to an acute viral or bacterial respiratory infection but there are also other causes as well.
Congestion and coughing is commonly related to rhinosinusitis which is inflammation of the nasal passages and sinuses
. These commonly occur together.
Infection causes inflammation but it can also occur due to allergies.
YOu may consider the use of a topical nasal spray
along with an antihistamine.
You doctor will be able to tell you which ones are available in your area.
I hope this helps
