For the past two months I've been having bad allergies. I first had a dry mouth/throat, now I have post nasal drip which is causing my throat to be red, I have congested nose and ears. I noticed after I took sudafed today that I have mucus like on my tonsil area. I don't know what else to do, I've tried every medicine and nose sprays already and I've been to 4 different doctors they all said its allergies. Please help!
