I have a son that is 9 years old and I have noticed a small painless swollen lymph node on his left hand. I would say it is definately less than an inch, but i dont't know the exact measurement. It is movable and not hard but not squishy neither. I have noticed this for about a month and his pediatrician says it is nothing, but it is really starting to worry me. Any answer would be greatly appreciated. Thank you.
