No worries: You should get into the habit of knowing how your body feels normally. Don't be afraid to examine ALL your nodes and more: neck - front, side and back, above the clavicles (get an anatomy book), bellow the clavicles, the armpits, the inguinal region and the femoral region - get that book! You can also feel your spleen-maybe, liver breasts and genital areas and remember to look at your skin.
