Does anyone know if we have lymph nodes on
the back of the arm. While scratching the back
of my arm today I felt a round lump about the
size of a large marble. (location) if you start
at the arm pit crease and go straight back until
you feel your arm then go over approx 1 inch
toward the outside of arm then up approx
1-2 inches up toward shoulder. It does not
hurt and it is not sore. It does appear to move
when you try to manipulate it with your fingers
