She didnt think it could be a swollen lymph node? Sometimes they get like that when you have a small infection somewhere. Here's the thing , whatever it is, it should go away in a couple of three weeks. If not, go to your internist, they see more of it. It is your body, if you feel iffy about it get a needle biopsy, chances are it is absolutely nothing. Where you just doing your monthly check when you found it? I dont now, nor did I ever believe the "sore or not" . Do not hear that I am saying you have something bad, just have another opinion, thats all I am saying. I had a few bumps a couple of years ago. They were ingrown hairs from using a cheap blade and drying soap.
As far as wasting the Drs. time.......it is why they are paid.

I would get them checked out for your peace of mind.

You're not wasting their time, you're safeguarding your health.

This is kind of weird, as my 19 yr. old daughter had me feel both of her arm pits for something she just noticed. What I felt was a small (about the size of a little pea) somewhat pliable lump under both her arms. She said that it hurts a little when they are poked.

I can't imagine that it's something serious (denial I know) as they are so small and symmetrical and she has recently been sick.

nodes shouldnt stay swollen more than 3 or 4 weeks, unless there is an on going infection or long lasting virus....So just keep watch on them.
