My 20 month old has a lump on his chest right benieth his collar bone about the size of a dime and another smaller one on top of his collar bone. The one beneath moves and seems to be right beneath the skin. The other one doesn't move and is hard. He has had the first lump about two months and seems to be getting bigger. He doesn't eat but drinks a lot. He started having sever diarea tonight(5diapers in 1-2 hrs. He seems to want to eat at times but stops very shortly after starting. Other times he doesn't want anything at all. His sleep is less as well. He turns pail on and off and the rims around his eyes are red. We had lab work done today and they say his calcium and iron are low. he weighed in at 24.2lbs today, from 26.8 on may 11. X ray came back OK, but ultra sound was no help. I am waiting on a referral to see a pediatric surgeon. I am not sure if that is the best next step. I am very worried about him. Any advice on what will help or who to see next?
