Throat pain. Taken to get rid of this.

Hello Doctor, I am suffering from throat pain which is very mind since one month. Initially the pain is severe with additional symptoms like pain while talking, swallowing, yawning or sneezing and pain behind right ear. Then, I consulted my nearest ENT specialist. After checking, I have diagnosed with GERD. He prescribed medicines GiLite (contd), Diovol-LA (contd), Claribid 250 (10 days). With these medicines my symptoms were reduced drastically. All my symptoms are disappeared except pain while swallowing. The pain happens only when I swallow saliva but not food or any other liquid. But the pain is very low still noticeable. The pain is high when I wake up in the morning, then after it reduced to minimum State. I have hypothyroidism and taking Thyroxin 50 in the morning first, then after 30 min I take GiLite. Please suggest me what is exact happening to my throat and what measures should be taken to get rid of this.
