Brief Answer:
Monitor progress + antihistamine...

Detailed Answer:
Hi,

The details you provided are very minimal to create an opinion. I assume there are no other symptoms and the symptoms are recent (a few days) ones.
In this context, I would suggest to try steam inhalation and antihistamine medications like tab cetrizine 10mg once at night time for 3-5 days. You can also take tab Dolo 650mg (if you develop fever) three times a day for a few days.

In the meanwhile observe and monitor progress. If you develop cough, bad throat pain, sore throat, high grade fever and others, contact your local doctor for further evaluation.

Hope this helps. Let me know if you need clarifications.

Regards
