My daughter was diagnosed with mono a week and half ago. She also has a swollen lymph node on her neck and it first it was just one big knot, but today I noticed that it is going into 2 knots and is starting to bruise up. I am wondering if I should be more concerned about this than I already am. I am a nervous wreck about my baby being this sick. She goes to the dr in the morning but I want some one else's opinion. Please help!!
