question: my 5 year old daughter was bouncing on her bed and fell and hit her forehead on the corner of the radiator 2 weeks ago. a large lump came up straight away and bruising. the lump went down a lot 2 days later. she was not sick or showed any signed of drowsiness. in fact she was fine. the lump is still there and very hard now 2 weeks later. should i be concerned?
