Hi, I was diagnosed with mononucleosis about a month ago and I have swollen glands in my Neck, one tonsilar and one posterior cervical. The tonsilar swollen lymph node is huge (more than a cm) and the posterior cervical is about a cm. they both have been growing since I got over my symptoms of mono, which I really never had many just an irritated throat for a day. They have become hard over the past week. Is that something I should be worried about?
