Hi!
A couple of years ago my lymph node on the left side of my neck swelled rapidly - and off to the doctor I went, like most people I became rather worried. The doctor ordered an ultrasound - and it was 8cms in diameter, but apparently was nothing to worry about. I was told if it grew more I was to come straight back but it still shrinks and expands, but has never ever gotten much bigger. Why it does this is a bit of mystery to me!
