I have a severe sore throat for almost two weeks, it gets so bad at times i;ve compared i to sandpaper inside my throat. it hurts when i swallow, caugh yawn, or breathe too heavily. there are times when it hurts so bad i just want to rip it out. i wen to my doctor who said it was nothing and wasn't even red which makes no sense to me. today i completely lost my voice at one point, and while it was gone i had no pain, but shortly after it returned so did the pain. what is this and what should i do???
