Had a blunt force trauma to my left lateral oblique from a fall saturday.my bruise is start out more yellow then a normal bruised should i be worried?

It’s OK: When we have a blunt force trauma, sometimes the bleeding can be fairly deep below the skin, so you will not see the bruise. That doesn’t mean there’s no blood, it’s just not on the surface of the skin yet. Typically if the bruise is close to the surface it will be reddish purple, then slowly change to a greenish color and then yellow before it fades completely. It’s all good!
