for about 3 weeks now, my throat has been killing me. and had headaches. it hurts on both sides of my neck,and really hard to swollow,and talk sometimes. i've tried chloraseptic andcepacol,and instead of making it better,it makes it hurt and burn worse.what is the cause of it. and is there a cure i could try to make it better. i tried a heat pad and it does make it fel better.
