They don't sound of much consequence, probably collections of fat or fibrous tissue. Even if they are lymph nodes, the fact that they're rubbery means they're unlikely to be of concern. Of course, you can't know for sure what they are without being examined, so please arrange to have that done.
Take care.

Is the lump in the groin, a 2-3 inches off of the inguinal line most likely a lymph node?
