I am a 23 yr old woman who has just found a small soft little lump on the back of her neck, on the right side near the bottom hairline, i have no other problems with my neck like no pain or anything, i am just wondering whether its anything to worry about? Cause the last time i went to the doctor for a little lump on the top of my chest and they told me not to worry and it has gone away now, so i dont really need to worry about it, do i?
