Sounds like the sorta lump I had when I had a blocked duct, I think you can still get them if your not nursing but I'm not sure. Get it checked out. If it is a blocked duct massaging it helped me.

Sounds like maybe a lymph node.

I would have it checked out by an MD though

I agree with the other ladies. You should get it checked for a piece of mind. It could be nothing,but better safe. : )
