Pesistent sore throat and glands for months - PLEASE HELP

I have no idea where to post this question and I am hoping someone can give me suggestions. My throat hurts so bad and has been months. Sometimes the pain feels like it is in my glands and makes my ears hurts as well (when the pain is severe). I have Hashimotos thyroiditis and have been assured by my doctor this is not the cause of the pain. I also do not have strep, an ear infection or any sinus related issues (confirmed by my ent). The ent suggested maybe it is acid reflux but despite the fact I know I do not suffer from this, I began taking meds for it anyway. Since I have started the acid refulx meds, my symptoms have worsened. The ent said my throat is extremely red. I have no fever and over all feel normal except for the pain in my throat and glands. This pain is SEVERE. Sometimes it feels like it is my throat muscles and not the throat. It does not hurt at all to drink or eat anything. But the movement itself from talking or trying to use mouthwash feels like my throat muscles are fatigued. Please help me!
