Slip and fall, cause for concern?
Basically my (56 year old) mother slipped and fell on her bad knee on a wet sidewalk. Her other knee was replaced a few years ago, and they told her this one would probably need it too. She insists she's fine and it only stings where she skinned it but that it looks pointy. It's swollen, there's bruising developing down her leg, and there appears to be a knot in her muscle. Am I right in being so concerned, or is it likely she would know if she broke her knee cap or something? We will take her to a doctor tomorrow if it's bothering her, but meanwhile I'm silently freaking out..
Thanks.
