Your artery probably just blew, purpose that the blood seeped out of it, surrounding the nouns and that is why it is swollen and blue. It purely happens sometimes, usually on ethnic group that are a hard stick. Even nation are that are excellent at drawing blood will blow veins once within a while. Sometimes, just a hypodermic entering the vein will blow it, other times it is when the plunger comes out. If the person have a hard time finding your find and fished around, that would be the result in. Or maybe they used the wrong size syringe. Either way, it's zilch to be concerned about, newly keep putting melt compresses on it and that should help it budge away sooner.
just bruising dont verbs put some ice on it
If it's bulging and swolen it most imagined means they blew the capillary and now you enjoy a hematoma.
Some blood leaked out of the capillary, nothing is wrong, it happen sometimes.
