Hi, I have a very bad pain at the left side of my throat. I've tried everything, the pain comes and goes but it's really bad during the night. It was accompanied by a cold about 9 days ago, the cold left after a day or two, but the throat pain stayed. I take a lot of Advil to help. I don't know what's going on. I tried drinking some orange juice an hour ago, it made it 10times worse.
