Cheryl,
I don't really know. If you would describe it as being the size of a bb which is what it sounds like, I've had something like that which first showed up for me towards the middle of radiation treatment. It did not show up on a ultrasound then, and I was not able to find it again afterwards. I was told it could be something from surgery. Nothing has shown on a CT scan for me either. From what you've said I would say it is probably nothing significant, but for peace of mind it is good to get it checked out.
