I have been diagnosed with hypothyroidism, and possibly sleep apnea. Over the last few weeks, my throat has been sore on the right side, its a burning sensation, and feels scratchy. It also feels like my food, or my pill gets stuck there in that spot when I swallow it. I went to my doctor and he gave me antibiotics for a sinus infection. After completing the antibiotics, the sore throat came back a week later. Any suggestions?
