Throat Pain. Seeming to get right only.

Hi I was having dry cough a month back. From past 10 days I am experiencing throat pain/burning sensation. I visited physician and was prescribed antibiotics (Azithromycin took for 3 days and Augmentin 625 taken for 3 days) but still my throat issue hasn't been resolved. I still have throat pain/burning sensation. I had feverish feeling (but temp not more than 98) and body pains for few days. Right now I don't have any fever, body pains, cough, cold etc. Only issue is throat. Physician had advised few blood tests which are as below. 1. CBC - Only WBC was abnormal with 12000 2. CRP - 11.5 3. ESR - 40 I visited ENT specialist also and he has written chronic granular pharngtis. How long does this take to recover still. Medication given is Ebast DC 2 times daily for 3 weeks Please help on my throat issue which is not seeming to get right only.
