In such situations I advice following:
1. Anti Allergic medication like Tab Levocetrizine once a day For 5 days
2. Anti pyretic like Paracetamol
500 mg thrice daily for 3 days.
3. Antibiotic like Azithromycin
500 mg once a day for 3 days.
4. Warm saline gargles 4 times A day.
This is my best advice for you. You will get better in 3-5 days.
