Just am curious as to why some bruising takes a long time to appear? I go running and last Wednesday went arse over tit really landing heavily on my left knee. I grazed it badly but it also felt really sore but until today and this evening there hasn't been much evidence of bruising, but Blimee, there is now!
Why has it taken so long to appear?! I would have thought as the result of a big bang it would appear quickly like they seem to in children.
As I said, not serious just interested!
