[|Human|] I had blood drawn yesterday morning.  By the end of the day, the area where blood was drawn was not only bruised, which I know can be common, but a very large area of the skin is raised significantly.  Obviously, during the process blood got outside of the vein, but should I be concerned by the size (egg) and height of the raisied skin?  My concern would be potential blood clot???Thank you.

If you have pain with this you may be suffering from thrombophlebitis (inflammation of vein). So, visit a doctor to get yourself checked for further treatment. No need to worry.
