Something stuck feeling back of throat.

I have a feeling of something stuck in the throat and it is going to be almost a month since I am suffering from this problem. I have taken up antibiotic course for it and medications like Maxtra P as per my ENT consultation. But I am not relieved with the lump feeling as it sometimes gives me gag reflex. I have orangish bumps in the back of the throat and the stuck feeling is felt near the adam's apple. I have undertaken hemogram test which gave my esr value as 25. My crp quantitative is 5.60 but my ige total is 1177.50. I don't think it is a case of strep throat as i dont have any swollen tonsils or fever or lymph nodes. Should I get a throat culture for this? What could be the reason for high ige? I am attaching a picture of my throat for reference.
