Growths under skin

[Kinetic]

Hi there,
I have had several spherical growths just under the surface of the skin of my left arm and both thighs for some time now. Sounds nice huh? The growths are not painful and do not appear to be growing, are hard and gristly to the feel and range in size from a peanut to a 1 penny piece. I have of course had these checked out by a GP who assured me they are simply lymph nodes that some people develop, however I would very much like more infromation on this. Cheers!

Grisly, hard....don't sound like lymph nodes.
Google....neurofibromas and get back to me.
