Hi, I had similar symptoms as you. Sore throat, painful swollen glands in the neck and under the chin (and ear pain - likely referred pain from the throat), low grade fever. This lasted for 3 months and midway my doc labelled it "the 100 day virus". I thought I was going crazy.....being sick all the time - esp. with the gland pain which I had never experienced so intensely. This year, I have heard many people had strange viruses....often throat-related, and long lasting.
You are going to the doc today, which is good. As the others have said, eliminate strep and get checked for mono - I did this as well. My virus lasted more than three months and I thought it must be something more sinister, because the symptoms came and went (but never completely) and lasted so long. If it is a virus...keep in mind it may not go away quickly. Good luck at the doc.
