When i was brat, i though in my body and blood have power ranger and the color changing bruise is depending on what ranger is fighting at that time

Thanks. I just randomly found a big burise on my arm with a yellow stop and it got me thinking. Is it infected. This is really helpful. Thank you.

I dropped something on my foot a couple months ago and it still hurts when I press on the area. I don't feel it at all otherwise though and I run and do lots of stuff on my feet. I don't even know if it's just the skin that hurts or if it's something else in there. Why would it still hurt after 2 months though? It wasn't even a bad injury, just a slight bruise. Also this reminds me of something else. A long time ago I got a very sight scratch on my arm that just barely broke the skin but it gave me a scar that I still have. It was the lightest little scratch. How does that cause a scar? I've had plenty of scratches like it that didn't cause a scar. Why did this one?

Many thanks for this. In terms of investigating a patient with bruising; they are usually caused by blood vessel trauma ie mechanical causes, platelet dysfunction or penia and finally coagulation disorders. You would send an FBC with a blood film, biochemical profile, and coagulation screen.
