The symptoms suggest that you might be having Allergic rhinitis
1. Antihistamine preparations like Fexofenadine
to provide symptomatic relief.
2. Antitussive preparations to take care of the cough.
3. Gargle with warm salt water to relieve throat pain.

If symptoms still persist...it will be better to consult an ENT specialist
Also make sure that you are well protected from cold, dust & other allergens.
Wishing you a good health.
Thanks & take care.
