My 10 year old grandson has what looks like a small what looks like an ingrown hair or pimple, with white head, on his neck. When he gets stressed, anxious, angry, etc., a clear fluid leaks from this spot. He says he has gills. He s had it since he was born. Also, I ve noticed when he s sucking on a straw, it pulls in on that spot. I ve asked the pediatrician, but he kind of just blows me off and doesn t seem interested. I just got guardianship of him so I want to try to figure out what s going on.
