I have a lymph node that be swollen and hurting under my jaw on the left side! It causes bad migraines, nausea, and sore throat! I've had it for two months now maybe little longer. It is very painful! I am scared that its cancer or something serious. I've had no help at my hospital they keep telling me to wait it out! Can you give me some advice on what it could be or how to treat it? Can thrush cause these symptoms?
