I recommend that you go to your doctor ASAP--don't let your fear stop you, as things will only get worse the longer you delay. Good luck to you.
Dear DebnDav, I am no expert on this, but I remember i had neck lumps pretty much all my childhood and now my two year old sons have them also and I took him to the Pediatrician and she said that if the lumps in the neck are mobile, meaning they dont appear to be fixed and you can move them around with your fingers and also if they dont grow, then these are fine. But by all means, please go to see doctor soon! All the best to you, God Bless!
