Thank you for your query at AskTheDoctor.com
I understand your concern.
Yes, allergies mostly cause this lumpy feeling in the throat. But a bacterial infection also needs to be ruled out. If it does not resolve on taking levocetirizine, then an antibiotic course will be required. So, I will recommend you visit your physician and get a prescription for Augmentin 625 mg twice daily for 5-7 days, depending on the severity.
Hope this was helpful,
