Our 5 month old has a small hard red lump (about the sze of a pea)under the skin on her shoulder, it has been there for about a week. Our Dr says that he doesn't know what it is, and has referred us to the hospital. He did say not to worry, as it would probably have dissappeared by the time the appointment arrived. But of course, I'm worried as hell. I just wondered if anyone could have any ideas what it could be, or if anyone elses baby has had anything similar. Sorry if I sound like a stupid paranoid mum.
