I have a couple in and around my neck...one has been there for many years and the other I only noticed about a year ago. as a precaution I had them scanned to find they were not swollen due to a reaction to anything indicating that they were just this size now as that sometimes happens after a previous infection. They are very small, around 1cm and they haven't changed at all, even after a bad flu, in over 6 months. I think I'm fine and my understanding from talking to my dr is that changes that were of concern would've happened by now. I hope this helps.
