2 and a half weeks ago my ds kicked one of those metal signs they have outside newsagents. (wrong I know, he was told very firmly not to but he does so enjoy pushing boundries) Instead of kicking it flat on he caught his shin on the side of it. Cue instant screaming and the bruise starting form instantly. Once we got home he was fussing about it for a while not limping or anything just being careful of it giving it the occasional rub etc thats it. I've not thought of it since really, untill I was putting him to bed tonight I caught sight of it again thinking well thats been there a while I rubbed it gently he flinched and said ow and there was a hard lump underneath the bruise. Now I promise I'm not being PFB for a start hes my third and 5 years old if that helps. Has anyone had to deal with a particularly stubborn bruise like this with a lump. It isnt showing any signs of healing now going yellowy pale around the edges IYSWIM. Do you reckon it needs looking at or should we wait and see?
