Hello just wondered if anyone knows what these could be on my sons neck (he's 2 years old) on his jugular vein ( both sides) I have been to the doctors and we are been referred. Has anyone else's child had these or know what they possibly could be. They are show up if he crys, strains, coughs, shouts, even running around. They are quite prominent, they are soft, pea sized lumps that show when he cryz etc, they are not easily seen when he's calm. Many thanks, Amber.
