I found a small lump in my armpit about two months ago, Dr couldn't feel anything and said come back if it gets bigger. It has gotten bigger (feels like a round ball) so I went today and he could feel it this time, he said it seems to be a lymph node. Have been referred for an ultrasound. Has anyone else experienced similar and what did it turn out to be, I'm hoping it's just because I'm pregnant and it is a hormone thing.
