Sounds like slightly swollen lymph nodes. It is always a good idea to get them checked out, but I am sure there is no problem. My son has one that seems like it is always enlarged. The doc isn't concered at all. Lymph nodes often swell when someone gets sick or is fighting off an infection (no matter how slight). You may not even notice her being sick if it is just a tiny cold virus or something - but those lymph nodes being swollen is a good thing. It means her body is doing what it should be to keep her healthy. They can also stay enlarged for several months, especially in kids who are alwyas meeting new germs - so don't worry if they don't shrink anytime soon.
