My ds hit his head whilst running around at nursery today, and a large lump appeared immediately. When I came to pick him up, the lump had gone down, but still seemed quite large. A few hours later, it was huge! His head looked deformed, bless him!! He said it hurt alot, but we managed to get a cold compress on it for about 40 mins, which took it down a bit. He doesnt seem at all concussed, but I cant remember which type of lump is good...soft or hard? Im assuming soft is good? His is very soft, so am thinking this is fluid or something which is protecting the injury? Any ideas? Should I have taken him to a&e??!!!
